seller not responding

[wanttosinglikemarycoughlan]

I have bought a collect only item off ebay, well I have won the auction
I messaged before I bid to say I would have to collect at the weekend and that was ok so I bid
I won at a very low cost, less that £20. A similar item in a different area went for £140
I messaged after the auction and said again I would collect at the weekend and asked for address and have had no reply
The seller has 100% feedback but I wonder if they are not happy at such a low price
Should I offer more, I would've bid up to £80 and do really want it

No you don't need to offer more. Why don't you get the details and phone the seller.

How do I get the telephone number?

Telephone numbers can be listed on the order (which is available via the View order details link on the More actions drop-down menu next to your item in the list of Sold items).

you can go to advanced search then find contact details and then enter seller id and item number.
