what you really have to watch out for/complain about, is the ASSHOLES in the front of the line have 1st dibs on ALL of the vouchers.
some of them got shady last year at the tuttle best buy and decided to take one of EVERY voucher, even if they had no intention of buying that item.
then turned around and tried to SELL the vouchers to the people further back in the line, they need to have some sort of system setup so that shit doesn't happen again
and as mentioned, watch out for line cutters as well, anyone not standing in line all night does not deserve to jump in line right before the store opens
i do this every year, BF it is crazy as hell, but it's kinda fun at the same time
needless to say, i bulled my way through and got what i was after
