I had a friend that worked a Z Gallerie who got me all my picture frame cardboard boxes before they were thrown out (the were the perfect sizes too). When they bit the big one, I thought I had lost my free box connection, but DUH, dumpster diving sounds awesome! Thanks for pointing it out because I never would have thought of it. Seriously, the boxes at Staples are a rip off, and even buying in bulk thru Uline means I have to stack them somewhere. Thanks!
