Why do people out "Best Offer" on their sales?

There's a rack unit on ebay, priced at £42.99, with a "Make Offer" button.

So I clicked the button and offered £40.

The seller declined the offer.

Huh - why put an "Offer" option there if you're not going to budge on price?

Agreed. The absolute worse for this are the Chinese sellers. If they are selling at £19.95 and you offer £19.90 they'll decline!
