Just get there at 6:00am and you will have all the help you need and no lines at the register.
Ha. I had to run by a Wal-mart Supercenter this week at 11:00 on a Monday night.
When I got to the registers, there was 1 register open with 6 people in line. All of the self-serve registers were off-line because they had no one up front to moniter them.
18 minutes to get checked out at 11:00 p.m.
