I've only ever bid at small village hall type auctions where you were charged a couple of £s entrance fee then simply paid whatever the winning bid was. I'd like to have a go at larger sales with a couple of local auction houses, now doing this online but don't really understand the extra costs involved.
For example, there's a lot consisting a crate of fabric offcuts, some bolts of material, other sewing stuff etc, with a guide price of £20-30. Then it states a Buyer's Premium of £20 including VAT. Does this mean that if I bid say £25 (and won) that I'd then have to pay another £20 - almost doubling the cost?
I get that the auction house needs to make money but thought that came from a charge to the seller and maybe VAT charge on the bid price from the buyer. I'm obviously misunderstanding something!
