These are auctions where a seller is selling more than one of a certain item. Dutch auctions can be done by bidding. Buyers bid a price and say how many items they want, and then everyone pays the lowest price that was bid by one of the winning bidders. If you have trouble getting your head around that, then don’t worry – everyone else does too! These auctions are very rare.

What is more common is when a seller has a lot of one item, and lists it using a combination of two auction types: a multiple-item fixed price auction. This just means that they say how many they have, and offer them at a fixed price. You can enter how many you want and then just click Buy it Now to get them.

After all this, you might find yourself facing a dilemma: when you have the option, should you bid, or should you just use Buy it Now and save yourself the hassle? That’s what the next email will be about.
