I'd worry more about the checkout lines, than any lines to get in trhe store. Their checkout setup in not "BF-Friendly".
I walked in last year 5 min after they opened. Asked as associate if they still had any Doorbuster snow blowers. They did, and he took me to a closed cash register, rang me up, and I was out of there in 5 minutes. The lines at the open check out stations were ugly and unorganized.
