How does Tova give Ethan the T-shirt she buys to replace his, and how does he respond?

Tova asks Janice to help her get Ethan a new Grateful Dead T-shirt. Janice helps Tova use the internet to find a shirt for sale online. They find one for $2,000. The man selling it would ship it in two to three weeks, but Tova goes down and picks it up even though she has to drive on the freeway.
