Been using Newegg/BestBuy for electronics, Costco/Target/Walmart for home goods, local grocery stores for food, and Barnes and Noble for books. I used to be good at picking out the gems from the cruft on Amazon, but either it's gotten more difficult or I've lost my edge.
Also kinda nice having to wait again until I have a sizeable order to get free shipping. Much less junk.
How does changing stores help. If the products are still the same but on Walmart, how are you getting better information?
