Fry's is simultaneously great by its selection and breadth of stuff they sell and bad with their clingy salespeople and not always great prices.
They do have pricematching but it can be tricky finding it on the proper website and seller, and then it involves a manual process to get it reduced.

Still it's a great retail place to browse in and to try physical devices (headphones, speakers, computer accessories etc) since their selection is so great.
Especially useful for a last minute cable or computer part that would take too long to get shipped.
