For every clam purchase made during the Home for the Holidays Event, you will earn stamps on your Stamp Card. The stamps you collect are based on the dollar amount of your purchase. Completing 5 stamps completes a tier. Completing each tier gives you a reward.

The stamp card progress during the event is cumulative. Any extra balance after completing a tier will carry over to the next tier. The value of how much you spend will accumulate during the event and will round up to the nearest dollar.

E.g. If you made a $4.99 purchase, you could complete 5 $1 stamps. The value of the stamps within each tier is listed on the stamp.

The tier rewards are as follows:

- Tier 1 Reward: 75 Clams

- Tier 2 Reward: Box of Clams

- Tier 3 Reward: Lord Doom
