true that this is a free site and isnt a spam, they make it a living nightmare to actually redeem anything. normally requires staying in front of the computer for abscene amounts of time waiting for a redemption that lasts what a minute at best? also they seem to only have about 5 of each item, limiting what you can get, since you are basicly now competing with about 4mil+ other users. crashed my computer once. I'm not saying its like this for all but, this is my take on lockerz.
