okay here are my to racking tips
1). go to home depo, they dont have the gates around there paint closed very tightly (ussually) and you can ussually swipe a few that way. blista if your from philly and if im not mistaken i think you are. go to the home depo on delaware ave. this is the best example of this one.
2). my secound one is if you dont want to deal with stealing or payign to much go to wall-mart this is the sexyest way to rack. they sell cans for 98 cents a peice and they ussually hqave kry or rusto heavy duty and you ask the man to open the cabenet, you get a load of both brands cheapo and name brand cans. this is the only part that you could get in trouble for doing. tell you man your gonna pay upfront and go find a shady area and switch the tags on the cans soo you can buy kry for 98 cents a can. oh and dont worry about age if you look remotely like an 18 year old theyll let you buy it. or get an older friend.
