This deal appears to be in-store (B&M) only. The deal advertised on the shelf sticker is "Buy 2 get 1 FREE" with a regular price of $3.99.
Buy 3 12-packs and pay $7.98 (2 @ $3.99/each, 1 @ $0.00)
Buy 6 12-packs and pay $15.96 (4 @ $3.99/each, 2 @ $0.00)
LIMIT 6 (shelf tag read limit 4 but I assumed that meant 4 at regular price and 2 free; the register didn't have any issues with 6 I bought in one transaction)
Mix and match flavors.
I did not attempt to apply any coupons in addition to the register applied B2G1 deal.
I did not attempt to purchase more than 6 12-packs in a single transaction.
NOTE: Recycling fees and tax will be added to the above price depending on location.
NOTE: The shelf tag indicated the sale as something like, "Buy 2 get 1 FREE". It also showed a "regular price" of $3.99. It did not show an effective price per unit (12 pk) with the sale price. I believe that price should have been $3.99 with a regular price of $5.99. Regardless, it rings up as described above.
