If you really want to save money on household type items, go shopping in the 'market' area at your local IKEA store. Compare that with Amazon prices for pretty much everything and you'll be blown away by how cheap IKEA is.
Depends how much you value your time. At least at my local Ikea it is very difficult to get in and out in less than an hour even when I know exactly what I want.
Don't know about the US but here in Germany Ikea has an online store, too. Shipping for non-giant non-superheavy things is 3.90€ so pretty okay. They're not as fast as Amazon, though.
..or you can order online then go to shop and collect your order for free. It's usually the fastest method (except going to the shop and look for things yourself). I hate shopping so this is my preferred way of getting things locally.
