Pretty much anything can be sold at auction, but usually, to make it worth it, people will sell larger or more valuable items. One category of items is household appliances -- from blenders to microwaves to refrigerators. Some of these items you may prefer to buy new (a used fridge, for instance, can be pretty disgusting if it wasn't taken care of), but others are just as functional when purchased second-hand. If you're looking for a reasonable price on a household appliance and don't mind that it's used, try out the next local auction.
Before you go anywhere -- whether it's to purchase a new appliance or to check out the auction scene -- decide what features you aren't willing to compromise on. Come up with a list of things you'd like to have in the appliance: functions, buttons, power options, color, size, etc. Unless you're absolutely set on getting the best deal, don't compromise on this list -- hold out until you can get the appliance you want, even if that means attending a bunch of auctions.
The process of buying appliances at auction differs depending on the size. Small appliances are easy to look over and test at the auction house, while larger appliances are more difficult to gauge. It's also harder to find used ovens, refrigerators, and dishwashers that are still good enough to auction off, and you'll want to check the inside to be sure it's clean enough for use.
Be sure the objects are working safely before you place your bids. Speak with the auctioneer about the condition of the appliance -- ask him or her if the owner has mentioned any flaws. Ask about a return policy or money-back guarantee in case the appliance malfunctions. Be extremely careful when first using appliances bought at auction -- you don't want them to explode in your face!
When you arrive on auction day, make sure you've got a way to take the appliance home. If you're planning to buy large appliances, take along a large truck or trailer to put it in, and when you arrive back at your place, be sure you've got plenty of help to move it; don't strain your back or arms trying to move it by yourself.
