Doydie, ebates.com is the best thing I've found on the Internet!
Since I do 99.9% of my shopping online it really helps to get a percentage back from each purchase. I think my biggest rebate maker is from the cat food and supplies I buy.
All you have to do is go to
www.ebates.com and type in the "search" box whatever online retailer you're planning to use to see if they are one of ebates participants. Most all I use are.
There are lots of FAQ's so most of your concerns are addressed there.
I love it and wouldn't shop online without it. I think my biggest rebate check to date has been $246. That is just from using websites that are part of ebates. I'm going to buy anyway.....may as well get paid to do it!
Here is the link to the site......

I hope you sign up and use the service. That little rebate check every three months is a treat!
