I am lucky enough to live right in the middle of two of the supercenter Joann's. One is a LOT better than the other. I will only go to the second if I happen to be in that shopping area.
I have never really had trouble at the cutting counter, some long lines on coupon events, but they move fast. However at checkout, it seems like nobody knows what they are doing.
Lol I will still go there though. I love Joann's.
