This is a tip really.
To find the cheapest item on eBuyer, you can click the link I will post in my second post.
I had to figure this out, and put it to use, because I needed to raise my order by 1p, to get the Google Checkout £10 discount - my order was just £29.99, where as the minimum spend is £30!
Currently the cheapest item is 16p exc. VAT. That's some power surge cable!
Hope this tip will save people a tenner when they want to take advantage of the Google Checkout feature!
I bought the GrooveBase iPod speakers, so thanks to Edi the OP!
