Buying on E-bay

I recently discovered the joys of buying on ebay and the joys of bidding. The tut-tut of losing.

Prices

We sold a three piece suite on ebay for 99p. A bargain. In poor condition. Buyer collects. A local shop bought it.

I've bought bargains on ebay. The postage pushes up prices.

I see dresses and sometimes email the seller. How long is it? eg 48 ins (knee length), 51 ins (mid calf). Pull on or zip up? Shift or bust darts?Fitted, elasticated, stretch material? Wash or dry clean only?

So far I've been lucky and I've always given positive feedback.
