Reselling on Poshmark and eBay is one of the few, zero to low cost businesses to start from your home. As you start to make sales, you will be responsible for shipping the item(s) that has been sold. Having the appropriate supplies on hand to be able to ship out in a quick and efficient manner is extremely important. Shipping speed can often be part of feedback and ratings on selling platforms, so ensure you’re doing your best to ship quickly and with the least cost possible. Many people are unaware that the United States Postal Service (USPS) provides dozens of FREE shipping supplies. Boxes, labels, stickers, and even customs pouches. Some of these items can be found in-store at your local post office as well as the full inventory online at the US Postal Store, including bulk ordering options. Let’s talk about a few options for your everyday reselling needs.

There are many sizes and shapes of boxes, envelopes and bubble mailers to fit all sorts of shipping. It’s important to get an idea of the size of your item to efficiently send in the mail. Most commonly, you will find Flat Rate options that are self-adhesive at your local PO. Priority Mail stickers and labels are best to be ordered online as these don’t often appear in-store. As you explore the supplies based on your needs, here is a list of go-to products that I would recommend having in-stock for day-to-day shipping across the platforms. Priority Mail Small Flat Rate Box, Priority Mail Medium Flat Rate Box (both the rectangle and non-adhesive square shape), Priority Mail Tyvek Envelope, Priority Mail Padded Flat Rate Envelope, Priority Mail Flat Rate Envelope.  These are the perfect sizes for your everyday clothing items like jeans, sweaters, shirts. When it comes to heavier, bulkier items, you will want to measure and use the appropriate box. For shoes, more rectangular or smaller oddly shaped items, the appropriately named Priority mail Shoe Box is available. This is a great box for Men’s shoes up to size 12/13, depending on how bulky they are.

**Specific to Poshmark, you are able to ship in any non-USPS branded box as well as all Priority Mail boxes, including flat rate and regional boxes. The USPS Express Mail boxes are not able to be used, as well as other shipping carrier branded boxes or mailers (ie. UPS, FedEx, DHL).


One final note. Because reselling can be heavily focused on sustainability, also keep in mind that you can recycle and reuse materials coming into your home, whether it’s from Amazon, Target or wherever you are shopping. Boxes, packing materials and bubble mailers are always floating around, so don’t be afraid to reuse them. It’s even worth mentioning to your neighbors and friends that you reuse the boxes/materials for your small business. More often than not, they will be happy to save or leave them for you!
