You can get a assortment of boxes right from usps.com for nothing they will ship you Priority boxes in boxes of 25. This is what I do as a seller and if you don't want to pay for the higher priority mail you just split the seam and turn them inside out. As far as Tape goes even if it is $6 a roll a roll will tape up alot of packages. The only exception to having to buy materials is if you have a really large Item then you put in your description that you have to charge them X amount of $ for materials and if a buyer knows this in advance they never Gripe in my experiences with having to do this. But I know I have bought a quart can and got nailed on the shipping charges.
***Wanted*** Always looking for Oilzum, Kunz, and Husky Cans, Signs and Smalls.
