I shop around for the best prices I can find, be it online or at a brick and morter store. My budget it tight and I'll spend it wherever I can get the best bang for my buck. More and more that is at my local Performance store. Between the Team Performance cash back and waiting for sales and coupons, I can often find what I'm looking for at prices better than online after shipping and handling charges. The head wrench here at the Plano store is excellent and I've never had bad service there. Several times I've had a salesperson advise me to wait on a purchase for a few days because a sale is coming up.
Go on, call me a shill and get it over with.
Oh and I often shop and Walmart too. I'm just trying to get by on what I have.
