Yeah, last year I was in line for almost an hour. At first, they ran out of carts and bags by the time I got into the store (I was probably the 50th person in line), but luckily for me, while I was staggering around with an armload of gifts, someone was kind enough to give me their cart, since they had fewer items they could carry.
This year, I'll probably skip it, unless there is something REALLY great to be had. I've seen most of what I want in the WM BF ad.
