For inexpensive commercially available chocolate, I love Ghirardelli's Espresso Escape, dark chocolate with finely ground espresso beans. It's yummy and cheap, perfect for that bit of chocolate I need in the afternoon. I prefer the bag of individually wrapped pieces (around $6) but it also comes in a 3.5 oz bar (around $5).

Lon doesn't believe in Valentine's Day since he says that every day is V-day. So, bring home a little chocolate for no occasion at all.
