If you,have multiple acounts and want to use the $5 off 10 more than once I think you will find that you need to delete the half.com promotion cookie(s) off your computer.
I went into greenpoints ,then to half.com bought a used video I wanted for 10.50 and 1.95 shipping less 5 coupon for a cost of 7.45 and got the 3200 greenpoints imediately.

the $5 coupon was in a pop up as you entered half.com. The code for the coupon was GREEN.
I do not think you get the pop up if you have the cookie.

Half.com is apparently owned by ebay which gives me a little confidence.
