No, but I'll give you a recommendation "before" leaving the shop, and that is don't buy too much before you look online. For $15 you can get an amazingly bright LiPo headlight and battery off ebay, you can save a fortune on pedals, on computers, on almost any bike component you can to think of.
bikeexchange.com is worth looking for specials on bikes in your local area and any number of online outlets like Chain Reaction Cycles are good for parts. I buy a lot through ebay, lots of stuff in fact.
