The company said it is selling summer collectible cups for $2.99 for a limited time.
Collectible cup refills are available in stores only for $1, the company said. Customers must present the original collectible cup at the time of purchase to receive the $1 refill, it said.
Refills are not available through online ordering, and no additional combo discount applies to the $1 refill, the company said. The offers are available while supplies last, it added.
