Also, if you're new to the site, you'll get an additional 75 free points. Just registering nets you 25 and to get the extra 50, just look for the box that says to join the eBay Green Team. Well you'll have to click it and join, not just look at it. I don't think your computer can read your mind…yet.
EDIT: Whoa, it let me enter the code above five times, netting me an extra 60 points! I'm not sure if these extra points will stay or if this is a glitch, but heck, you might as well try.
