Possible free Heluva Good dip at Tops

I ran into Tops today to grab some Silk Almondmilk (not on sale, but there is a coupon here) and noticed a possible freebie.  The small (8 oz.) cartons of Heluva Good French Onion dip are on sale 10/$10.  There is a link on the Heluva Good website for a $0.50 coupon (look for the coupon link in the lower right corner - it looks like it's cheese, but the coupon is good on any of their products).  The link goes to a Red Plum coupon, but I'm getting a webpage error after I click the print button.  If you can get the coupon to print, it'll mean free dip after the coupon doubles!
