sent an email to the seller and got this back , which gave me a big smile :
Hi Dale, if you put a bid in at £18 there's a chance you'll get it for that and I'd be happy for you to pick it up in person so you wouldn't have to pay postage. If however you don't want to wait till Sunday and would rather buy it now I'd accept £25 for it. I'm happy for you to pay cash on collection if you want. It's unframed but if you want, for another £10 I can put it in a frame with glass.
Please let me know if you definitely want it and I 'll end the auction and send you my contact details.
