It's just a Hy-Vee Liquor promotion. You get a punch card and get a punch for every 4/6 pack of craft beer or growler fill you get at Hy-Vee. After 6 purchases you get the 7th half off. The card says the max discount is $5, but sounds like some may be more generous. Ask about it mext.rime your in a Hy-Vee Liquor.
Same program - he mentioned theirs is better than some other Hy-Vee's as they go up to $8, and allow the discount on 12 packs (not just 4/6 packs).
