I spotted an album I fancy, on eBay so I put in my Watched items where it's sat for a few weeks.

Yesterday I decided to contact the seller to see if they'd consider an offer, close to the Buy It Now asking price. 

Anyway, the seller replied to say 'Hi Rob, thanks for your interest. I can reduce 10% total price : 60USD + 13USD =73USD -10% is 65,7 USD or 48GBP.........'

I replied to say thanks etc and if they sent me invoice I'd pay immediately. 

I waited and waited for hours, into the evening. 

Eventually when I checked the item I noticed it's price had now increased to 72USD 

I messaged to say I'd noticed that the price of the item had increased ?? 

Not had any response as yet and not holding my breath. Is it a mistake ?  We'll see - very strange......
