Seller Registration + Guide

Welcome! We are so excited you’ve decided to join us at our next event!

  • Our sellers keep at least 70% commission on their sold items! Keep a higher percentage by joining our team and/or referring your friends!
  • Each seller pays a small $15 fee to help us cover the costs of holding our sale event. To learn more about how we use seller fees, click here.
  • Seller payments will be issued via electronic check within ten (10) business days of the last day of the sale. If you choose to participate in our Drop & Go Tagging Service, your supply fee(s) will be deducted from your seller payment.

Click here to register (Seller registration opens approximately two months before each event)

Now that you’re registered you’re ready to start prepping your items!

  1. After you complete registration, consider signing up as a team member – you’ll keep an additional percentage on your sold items + get first dibs on quality items in the Next Size Up!
  2. Check your items against our safety page and our what we accept page to make sure that your items are acceptable and safe.
  3. Head over to our merchandise  and clothing prep pages to help you prepare your items for a successful sale.
  4. Price your items. Use our pricing guide when considering a price for your items. A good general rule is to price items 1/4 – 1/3 of the retail price.
  5. Enter your items using our free, online inventory system. Our tagging instructions page will guide you through this process. The portal will close for our spring+summer event on Thursday, March 27, 2025 at 6PM. After this time you will not be able to input new tags, but you’ll still be able to view and print tags after this time.
  6. Select a drop-off appointment by clicking on the consignor homepage, then click on ‘Select a Drop-off Appointment.’ Please sign up for a 15 minute slot per every 100 items you have.
  7. Drop your items off at the sale location during your drop-off appointment. We will inspect your items for safety and quality during this time.
  8. If you chose to pick up your unsold items, you can do so on Tuesday, April 1, 2025 from 7-9PM.
  9. Get paid!

What people are saying about the NSU Kids Sale:

"Love this sale! Everything is priced right, big variety of items, and the staff is super friendly!!! It’s the only consignment sale I go to in the area any more. Couldn’t ask for better!" - Stacy, shopper

“I loved volunteering at the NSU sale, it was great to earn the extra percentage! I will definitely volunteer again!” Amy, volunteer

"This has been a great sale opportunity for me. It is so nicely organized, planned and run. I get great results and it is a pleasure working with Ashley!" - Natalie, consignor

“NSU helped me save a tremendous amount of money shopping for my daughter – thank you!” Lisa, shopper

"I LOVE Next Size Up Kids Consignment Sale!! It makes my life much easier! I love that I can print tags from home, set my price and have the option to discount and/or donate! I have such good luck selling my kids clothes and toys at this sale. So much better than having a garage sale! I especially like how particular they are about the clothes and toys that come in. They are great at identifying stains and take pride in the the items they are about to help resell. I don’t want to shop around in junk, like a few places I have seen! All the workers have been super
friendly! I would choose no other consignment sale! Thanks Next Size Up Kids Consignment!" - Alison, consignor, volunteer & shopper
