I can only say that going to Costco is an enjoyable trip. Not only do I find 'almost' everything I am looking for, I get it at excellent prices. Whether it be food, electronics, books, movies, clothing, equipment, etc. It is at Costco.
I bought my iPod for $10 less than ANYWHERE (including the apple store). AND, I know that Costco has one of the best return policies.
Don't forget to eat, while you are there. They are almost everywhere in the country and (thank heavens) they are expanding!!!!
Can anyone do it better, I think NOT!
