I'm telling you, if you haven't signed up for ebates you are losing out.
A check each quarter for anything bought online? Sign me up. You should sign up too. Even if you're buying something from Lowe's or Home Depot. Looking for a grill...how about $100 off, free shipping and a 5% rebate sent back to you for buying it online instead of walking into the store and lugging it home?
Even Groupon.com and Target give 6% rebates for buying online. Don't leave money on the counter, sign up to get your rebates here. Oh, you also get a $10 gift card for signing up.
