I went and got this deal a few days ago.
I know there are some coupons you can print on coupons.com if they are still available.. but the easiest way to get this coupon is to buy All You from walmart.
The All You magazine is full of coupons and one coupon for the march/april issue is
$2/2 Mars candies.. so if you take this coupon to Walgreens this week and get 7 of the Snickers Eggs which are on sale for .29 then all you pay is tax. Which is not a bad deal at all.
