Kroger is giving away $4 to use on whatever!

I don't have a link or whatever, I just went and did this on Kroger (.) Com  Easy enough for Four Bucks!

I logged into my online account with Kroger (that is hooked up to my Kroger savings card) and I saw this banner

I clicked where it says Tell 4, Save $4.  Once you click that you pick out 4 of the products that come up and load them to your kroger card *(digital coupons)*  and then the next page I had to put in 4 names and 4 emails, and after I did that It credited $4 to use towards anything in their store to my Kroger Plus Card!  Whoot! Nice Find!
