I promote this for a couple of reasons -- one is that, yes, I also get a bonus when someone signs up through my link. But also, I post it on "Crip Chronicles" because I think that if you have any kind of mobility impairment and you're not doing the bulk of your shopping online, you're really missing a great boon to your quality of life.
Secondly, who needs a little extra money more than we do? They've got so many store listed now, that it is easy to get a little cash back on a lot of things -- just this month, I got rebates on my groceries at Safeway.com (yes, it is only 1%, but that's 1.15 I didn't have before), on filing my taxes at TurboTax, and on slippers from FootSmart.com.
