You have probably heard of the website, Ebates. If you're already a member, you probably know how awesome it is.
You join the website. Any online shopping you do, you do it from the website. For example, if you want to buy something from Sephora, you log onto Ebates, search Sephora, and click the link. It takes you to Sephora's website and automatically applies any coupon codes they have on file. In addition, you get a percentage of cash back put into your Ebates account. Most are around 6%, but some are as high as 30%. You get the cash in your account in a few days, and they send you a check in the mail 4 times a year.
It's legit. I've been a member for a year and I've got $80 in cash back so far.
Anyway, in addition to cash back for buying stuff, you also get cash back for referring new members. So if you haven't joined yet, you can join at this link:

Pretty much every online retailer you can think of is on there (except Amazon because they are whores).
Happy Christmas shopping.
