I don't know if restaurants do this on purpose, but I've started seeing this happen more and more often. Restaurants are startng to offer a half off deal at more than one deal site. Last week, it was Monsoon. Today, it's Kamon Sushi (16th & V).

• $7 for $15 (New Living Social users | existing users) at Kamon Sushi. Offer expires today.
• $15 for $30 at Kamon Sushi. Offer expires on Tuesday.

Other Deals:

• $10 for $20 to Level Up Lounge. Offer expires on Tuesday.
• $26 for $60 at Vanilla Bean Bistro. Offer expires on Thursday.
