I hate wasting time on sites like ebay, but inevitably get sucked into them every now and then. I'd gladly pay you ten bucks a month to surface stuff I might want, even if I had to do some initial setup work.

For example if you see an X61 with the SXGA+ screen on a buy now price, I want to know (rare as rocking horse poo). Or Lego with at least 30% off is always good for my boy or birthday presents.

You'd need to err on the side of caution, because I'd rather miss stuff than be spammed, but thankfully that makes your job easier!
