BestBuy
Best Buy Co., Inc. is an American multinational consumer electronics retailer headquartered in Richfield, Minnesota. It was originally founded by Richard M. Schulze and James Wheeler in 1966 as an audio specialty store called Sound of Music . In 1983, it was re-branded under its current name with an emphasis placed on consumer electronics.
Buydig
Buydig is an authorized retailer of all of the major electronics brands. They only collect sales tax in New Jersey, so when a price is fixed (say a new Samsung TV), you can save a little bit of money going with Buydig vs. a big box store like Best Buy.
Newegg
Newegg is the best place to go for all sorts of nerdy items- motherboards, graphics cards, etc. Their selection of computer parts is unparalleled, and if you sign up for their newsletter, you get access to daily coupons.
Walmart
Walmart sells virtually everything you can think of, from produce to tires. Given their buying power, prices on items like tires are better than you will find elsewhere.
