There is also one other way you might get things cheaper at the LHS, even if they match Tower. Ask if they will give you a better deal with cash instead of a credit or debit card. My lhs gets tacked with another 6% because of card transactions. If you tell them you are paying cash, they will lower the price to recflect not having to pay the credit card company. My lhs is a small mom and pop store that has been in bussiness for about 50 years. I spend a lot time and a LOT of money there. And since I do, they will usually not only give my the cash deal, but can beat tower by several dollars every time. But also some items just dont have much of a markup like OS engines. When you see what Tower prices them at, usually there is not much room to play with the price other than going up and there are a few other products like that too.
