No question about it. [Pause] I'm sure it's possible that if you spend enough time shopping from vendor to vendor that eventually you might find someone with a lower price on this particular item.
The question is, "how much" will you save on the whole and at "what cost"? The costs could be your time, the hassle of shopping store to store, and what about the quality of service after the sale.
Keeping all of this in mind, could shopping around really be worth the few dollars you might save?
