This showroom effect can work even for non-fitted items. I've repeatedly shopped in big box electronics stores then checked Amazon, NewEgg, and such on my phone from the store. It works out great, actually, because most of these stores match prices including the major online sites and have for years. If Best Buy, Fry's, or MicroCenter are cheaper than online, I win and they win. If they'll match then I win and they get a smaller win than if I paid their full asking price, but it's still a win. If for some reason they can't match and it's a small difference I might buy locally anyway, especially if I want the item faster than the shipping on that item at the particular online vendor. If the online retailer is far cheaper and can't be matched, they win.
