Free USPS Boxes

Best boxes to use are the free ones, am I right?

When shipping Priority mail packages for ebay, Mercari and Poshmark, I try my best to use USPS Boxes. Click on the link, make an account and order your boxes. I reorder often before running out. Shipping times can vary, depending on the time of the year, so plan ahead. Here is a list of the ones I keep in stock.—oshoebox-P_0_SHOEBOX—1096l-P_O_1096L—1097-P_O_1097—1092-P_O_1092—7-P_O_BOX7—4-P_O_BOX4—1095-P_O_1095
