Don't be a sucka! By shipping smaller sizes of sneakers or shoes in padded flat rate envelopes, you'll save your customers bread and get more sales. The average price of priority mail coast to coast 2-3lbs is about $20. In a flat rate envelope, only $8.40(correct price). What do you think your customers rather pay? $20 or less than $10. My advice: use clear polybags to protect the sneakers or shoes from dust, fingerprints or getting any type of marks on them. click the affiliate link below. https://amzn.to/2GJo1e9 Like and subscribe Fam! https://www.etsy.com/shop/FuturisticVtgTees
