Just wondering if there's anyone around Fort Wayne,(Indiana)who I can purchase some shipping boxes off of.  I'm not the power seller that would need 50 of one type, but 3-4 of a few types would really help me out.

Bump, just wondered if anyone could sell me 15-20 varying size boxes, I'd pick them, my collection is smaller and I'd really like to not have to buy sets of 20-50 boxes of one size.

Go to Walmart and ask if you can have their boxes. Sounds easier than what you are asking. 

It would be much easier for me to pay someone for specific size boxes that are unbuilt who have quite a few already, than to showup at a Walmart and search through used boxes in the stocking area which probably won't even be allowed.
