A bunch of us went out for drinks after work recently, where we met Michaela — girlfriend of new Groupon employee Dan Jessup and long-time Groupon customer. Michaela told us she had bought a few Groupons, but we thought she was exaggerating until she unveiled The Envelope. She has about 20 Groupons in this thing, and carries it in her purse so she never misses an opportunity to use a Groupon. She also cleverly writes all the expiration dates on the back of the envelope. If you have a cool way of tracking your Groupons, let us know!
