Walmart has 40-Ct Doritos Snack Size Chips (multiple flavors) for $15 each. Each comes with a $14 Fandango promo code toward a ticket to the new Spider-Man: Far From Home movie. There's a limit of two free ticket codes per household.

No pickup available, so your best bet is to buy two 40-packs of chips (and get two ticket codes), then add a cheap item from Walmart for about $5 to get to the $35 free shipping minimum.
