Presumably most folks here know about Cabela's and the Bass Pro Shops as good places to buy things like cast iron, deep fryers and sausagemaking equipment, and Marshall's and T.J. Maxx for pots and pans.
Yesterday, I came across one that's new to me:
Tiger Direct. Mostly a place to buy computers, accessories and parts, Tiger Direct has a small but very well priced selection of small kitchen appliances such as coffeemakers, ice-cream makers, food processors and microwave ovens. You won't find more than one or two brands of each type, but some of them are refurbished models at steep discounts.
