Restaurant.com offers discount gift certificates every day. Usually, you can get $25 gift certificates for $10.
But, through today, if you use the coupon code MOM at checkout, you can get a $10 for just $1.60 or a $25 gift certificate for just $4.
Make sure you read the fine print on the gift certificates before you buy, as some require a minimum purchase or are only good on specific days of the week.
At this price -- you could buy Mom a week's worth of dining out without breaking the bank!
