There is a nice deal today from Restaurant.com. You can get a Restaurant.com voucher for $25 for just $2. In addition, they are offering a free $10 Restaurant.com e-gift certificate with purchase! So you spend $2 and you should get a $25 voucher plus the $10 bonus voucher.
According to the fine print on this promotion, the $10 e-certificate will not be in your shopping cart but will be emailed to you within 24 hours of purchase.
Just head over and select your restaurant and use code: TASTY at checkout.
Typically most restaurants will require a $35 minimum to use the certificates- so you can expect to pay $10 or so after your gift certificate for a $35 meal.
Also they will automatically add on the gratuity of 18%. Just check the fine print on the restaurant you select but overall I usually get very good feedback about these offers!
Head over to Restaurant.com to have a look. Note there are a handful of restaurants that are slightly more expensive. You will see them listed as $25 for $15 before you enter the promo code. Those work out to $3.
Here is the fine print on the bonus $10 certificate:
For each order you make during this promotion, you will receive a Free $10 Restaurant.com eGift Card. The code for your Free $10 eGift Card will be emailed to you within 24 hours (and will not appear in your shopping cart). This offer excludes Dinner of the Month and physical Gift Card Purchases. The FreeeGift Cards can be redeemed online at www.restaurant.com for a restaurant specific certificate. The Free eGift Cards cannot be redeemed at any restaurant. Restaurant.com is not responsible for undelivered, lost or stolen eGift Cards. This additional offer is valid from Monday, March 28, 1:00AM PST thru Thursday, March 31, 2011 at 11:59PM PST.
