$4 for most $25 Restaurant.com Gift Certificates! Use code “DATENIGHT” at checkout now thru 2/9.  Not the cheapest rate right now, certainly, but if you’re looking for a voucher to use around Valentine’s Day (probably won’t be able to use it on the exact day), you’ll get the largest selection early in the month.  Wait a few weeks and the price drops a buck or two, but many restaurants have already hit their limits.
