That's the idea behind yougotbeer.com. It works like this according to the site:
1. Enter the name of a friend you'd like to send a beer themed e-card to
2. Your friend picks up the e-card and if you included a gift card for beer, they choose a bar/restaurant from our list.
3. We send your friend a $5 gift card for their chosen bar/restaurant so they can enjoy a BEER compliments of you!
If someone wants to try this out, I'm sure email@example.com would gladly accept your gift 🙂
UPDATE: Thanks to Jason for sending me a card! I've chosen Hops since they have some good brews. I'll definitely be sure to post the review here when I redeem the card.
