I have earned ~ 5,200 in cash back for the last 7 years, using 6 or 7 different cash back sites, so I know the rules and am always very careful. Please, be careful too when using ShopAtHome as your cash back platform. I have experienced so many problems with them that I stopped using them as my go-to cash back site. Recently, they refused to credit my account for an order placed on Amazon.com. The reason they gave me makes no sense. The more I tried to explain why, the more they argued with me. I think about 1/3 of my clicks are not paid or result in incident tickets. I never experience any issue with Ebates.com for instance. I cannot possibly make mistakes only when I use ShopAtHome.
Should you experience a problem with ShopAtHome, they will tell you that the merchant did not credit ShopAtHome for your order. It's usually the answer they always give. Be suspicious and don't believe them.
Another problem. I contacted ShopAtHome about cash back not being credited, and the customer service rep who dealt with my case/ticket kept arguing with me, spamming my inbox with more and more emails to make his/her point. I have never seen that before. This is highly unprofessional. So disrespectful!
