All have been mentioned above that I can think about, frys was ok but very much the lower end of the market as were most of the large chains I visited like best buy 55-250, 70-300's no L lenses. On strip prices are not competative and they are very un helpfull as nothing has a price on it so you need to ask prices for anything and the chances of stock are slim they have whats on the shelf.
The ritz outlet was pretty much empty with 1 or 2 lenses on the shelves. lots of things like cases and bags but not many lenses. and prices were not that great they had a 70-200 2.8 non IS and wanted $1400 for it when i went.
