Like most things, it pays to do research ahead of time. I like the denim jeans from Walmart/Sam's Club, but I wouldn't buy my shoes there.

While I am talking stores, if any of you have the Fresh & Easy chain of stores nearby, I highly recommend them for fresh food. They are the US chain of stores owned by the UK company Tesco. My wife and I have been getting most of our non-bulk food from there for several months and it is very good.
