matt76, I also buy almost everything online. Since many do not have the tax this makes it about the same price with the shipping cost. Also you can look at 100 stores at the same time and find the cheapest prices for the same item.
Many times they offer coupons to add to the cart system for 10 to 20% off. I sometimes find cheaper prices online in the same stores if I went to like Walmart has many items cheaper online. This goes for many stores online.
