I went to my local BB today and asked about this because I was curious. At first, the salesman himself also thought that it'd be a good idea just to buy the item today & get a price adjustment on BF. However, just to be safe he went & asked his boss. His boss said that you would only be able to do a price adjustment if the item was still in stock when you got there on BF & if it was a voucher item you would need a voucher to make the adjustment. So since you have to stay in line anyway you might as well just get the item then & there! You will also avoid 15% restocking fees on larger items like computers or TVs. As for myself, I'm heading up to my BB @ 11PM. For where I am, I'll probably be about #20 - #40. Not to worried about the voucher thing though, I'm aiming for the $699 Gateway. Don't get me wrong though, I'll definitely get a few things if I do receive one !
