threadUP, Poshmark, and Mercari

When I was pregnant my coworker gave me a trash bag full of clothing, a nursing pillow, two swings, and said to me, “You’re going to learn about the wonderful world of the hand me down mom network.” As I got closer to my due date the hand me downs grew as well as all the new things we were gifted at our baby shower from family and friends. I will be forever grateful for these. They truly helped us get through Noah’s first year and it was appreciated so much to feel the love and support.

I quickly learned that Noah outgrew clothing and gear fast leaving us with a lot of gently used items and not sure what to do with them. Trying to pay forward as much as we could we were able to pass on swings, baby carriers, and lots of clothing to other expecting moms. There is only so much you can pass on though as these expecting parents were also getting hand me downs and gifts from other people too.

I sought out some local charities, I posted a few bigger items we had purchased on Craigslist, and offered some things to local mom groups on Facebook. Then one day I was watching stories on Instagram and a friend posted about sending stuff to threadUP. I had vaguely heard about them but didn’t really know what it was about. After looking into it I decided this would be a perfect opportunity for me to test out the site along with some other resell sites. Here are all the pros and cons including my experience with threadUp, Poshmark, and Mercari.



threadUP is an online consignment platform. You first start by ordering a free clean out kit. They only accept about 40% of items sent. You can choose to have them donate what they don’t decide to sell or pay $10.99 to have them ship those items back. Then they send you a bag with a prepaid shipping label. In the bag you put cleaned brand name clothing, shoes, and any accessories you want to sell. Seal the bag up, drop it off at the post office and let them do the rest.


  • They take photos of the item and list it.
  • You do not have to worry about communicating with sellers or shipping.
  • Communication is great! They send emails to update you where they are at in the process, when items sell, and when items don’t sell.
  • Once they have gone through your bag and selected items they send you an email with a link to your items. While they have suggested prices listed, you are free to change the prices if desired.


  • You must pay a fee for items you want returned that they choose not to sell.
  • You must also pay a fee to have items returned that don’t sell within 60 days of listing.
  • They have percentage off coupon deals on their site and if a customer uses this then it eats into your profits.
  • Payout is low depending on the price point your item sells for. The largest return you can get is 80%, but that is only for items that sell for $200 or more. For instance if you have a pair of baby pants listed at $5.99 your pay out is $0.27.
  • They charge fees to transfer your funds to your bank account or PayPal.


Poshmark is a social commerce marketplace for fashion where you can buy, sell, and share your personal style. The social aspect allows you to follow other sellers, obtain followers, and share listings from other closets with your followers. They also have virtual shopping parties where you can share items with your closet that pertain to the party themes (e.g. Best in Jewelry, Designer Wear, Best in Maternity, Everything Kids, etc.).


  • When you make a sell, they provide you with a pre-paid, pre-addressed label to easily put on the package you are shipping.
  • The social aspect allows you to share your closet with friends and family or on your social media outlets.
  • Seller and buyers can create bundles of items with a “reduced price” to purchase.
  • Poshmark takes an even $2.95 commission on all sales under $15 and a 20% commission on any sales above $15.
  • Buyers can submit offers on items and you can accept or counter their offer.


  • Not a huge con, but you do have to take photos, list your items, and deal with packaging and shipping.
  • There’s a bit of a learning curve. I still don’t fully understand shopping parties. I’ve only participated in one and am unsure if my item received any more exposure than it has in my closet.
  • This platform is very social focused with an emphases on following, sharing, and engaging with others on the platform. If you don’t have a lot of time (like me) it can be hard to invest in another social platform.


Mercari is a selling app where you can list pretty much anything you can think of from fashion, toys, sporting goods, electronics, and household items. When the item sells you have 3 business days to package up the item and drop it off for shipping. Once the item is received the buyer rates the seller, then the seller rates the buyer, and your funds are released.


  • Mercari charges a 10% flat selling fee, which means you keep 90% of the listed price.
  • Rating the buyer and seller can provide a level of trust for potential future buyers looking at your storefront.
  • You get to choose if you will be offering free shipping or passing on the shipping charge to the buyer.


  • Not a huge con, but you do have to take photos, list your items, and deal with packaging and shipping.
  • Only way to promote or boost an item after listing is by dropping the price.
  • If item is not selling you need to delete and relist with a new title or photos to put the listing in front of shoppers again.
  • There is a $2 fee if you transfer a balance to your bank account that is less than $10.


I first want to preface this with the fact that different items were listed and sold on different platforms. With that in mind, this could never be a true equal comparison. Items included a variety of baby clothes, women’s clothes, and women’s shoes.


I sent a total of 27 items including baby clothing, women clothing, shoes, and some accessories. threadUP usually accepts 40% of items sent and they kept 63% of my items which I thought was great! Items were listed for 60 days. A total of 12 items sold and 8 items did not sell. My final payout was $10.72.

I have 14 days to reclaim any items that did not sell. To reclaim the 8 items that did not sell I would pay $5.99 in shipping and my total profit would then equal $4.73. Had I paid the original $10.99 when I ordered my bag to have items returned, I would have been in the negative. There is also a fee depending if you transfer directly to your bank account or to PayPal. To transfer to your bank account I would receive $10.31 and to transfer to Paypal I would receive $10.51 once fees are taken out.



On the first day of listing I immediately sold a bundle of 6 items of baby clothes. The total of the bundle was listed for $56. The buyer offered $40. I countered with $45 dollars and she purchased it. My final payout was $36. It took a little bit after my first initial sale, but since then I’ve I’ve sold 3 more items. My final payout thus far has been $174.



The first week of being on Mercari I sold two bigger ticket items and a bundle of 12 month pajamas. Since then I’ve had a pretty consistent flow of buyers on Mercari and I’ve sold a total of 8 items and have 4 items currently in progress (purchased and shipping to buyer). My final payout thus far is $153.08 with $37.46 in progress totaling $190.54.



For me personally, I probably won’t use threadUP again. While I love the ease of not having to worry about listing items and shipping, their commission fees are too high and it doesn’t end up being worth it. I’d rather donate the items. If you are someone who does not want to worry about listing, packaging, or shipping, this would be a great option for you!

I will continue to use Poshmark. Although I’ve only had a few sales, I think the social aspect gives the potential for future sales. I also really like the ease of not having to worry about shipping costs.

Ultimately, my best experience has been with Mercari. I’ve made the most sales on this platform without having to put in any work on being social on the app. As a mom, I appreciate the minimal effort needed to get exposure.

Have you used any of these platforms? Which ones are your favorites and do you have any tips or suggestions for others?

  1. I’ll keep these in mind. I have tons to sell. I would probably check out Poshmark first. I’ve heard the most about that.

    1. I heard the most about Poshmark too before I started. threadUp and Mercari were newer to me.

  2. I have purchased from Thred Up but have never used any of the others. I love how honest your review was of each one. Sounds like Poshmark is a winner.

  5. This is great! I use Thread Up all the time because I don’t have time to deal with the work of Poshmark. You’ve now convinced me that it may be worth the time after all. Mercari sounds like it might be a winner. Thank you!

    1. I totally get it. threadUP is very nice for the time factor when you don’t really have time to deal with it. The other sites are better on the commission part though.
