I absolutely love using Restaurant.com! It is great to save a TON on date nights and family nights AND these make great gift ideas and stocking stuffers too! Going out to eat with 2 adults and 2 kids can be super expensive but not when you buy your gift certificates ahead of time for a HUGE discount!
For Cyber Monday, Restuarant.com offered a $25 restaurant gift certificates for only $2 by using promo code CYBER at checkout but they have extended it through today! This is a HUGE savings because normally these are $10 each and I have seen them as low as $4 but $2 is just CRAZY!
There are tons of local deals as well as national deals so if you are planning a vacation, search for restaurants in the area of your vacation and save on food while travelling!
