It’s best to sign up for several shopping sites. You will get a greater variety of stores and you can refer friends to different ones to earn more money with shopping sites.

Here are some to try:

BigCrumbs
ShopAtHome
eBates
MrRebates

BigCrumbs is one of my favorite ways to earn money with a shopping site because they pay for referrals up to 5 generations deep. Read more about BigCrumbs here.  BigCrumbs Info.

ShopAtHome is a super easy, no nonsense site with great values. You get $5.00 when you sign up instantly. For each friend you refer you get $5.00 and so do they.

eBates pays $5.00 when you sign up and pays $5.00 cash or $10.00 gift card to the friends you refer.

MrRebates gives you a $5.00 sign up bonus. And a generous 20% of the rebate amount of the friends you refer at no cost to them.
They also get a $5.00 sign on bonus.

Each site has text links to send to your friends in emailsso you can earn money with shopping sites. Some have banners and other widgets you can add to your blog or website. Referring friends is an easy way to earn money with shopping sites. And the bonus is you also get a discount at hundreds of stores like Victoria’s Secret, Best Buy, Target, eBay, Shoes.com etc. depending on the shopping site.
