I was in Comstock Park this past weekend, and stopped in at Wal-mart twice while I was there.
This store seemed overly crowded, and for having so many people in it, there were only 2 lanes open with cashiers. That, of course, made the wait to check out at close to 15 minutes.
The store was very disorganized and messy looking, which makes it look dirty. I'd recommend finding a shop away from Alpine if this doesn't interest you.
