I bought several restaurant coupons, mostly $25 for $4 coupons. I bought for 15 different restaurants. Over time the restaurants stop participating or they only accept the $10 ones. I have over $4000 worth the coupons because there's not much around my area anymore. I bought OIP pizza restaurant 2 days ago. I exchanged coupons for 30 $15 off a $22.50 purchase. The very next day, they stop participating. They were in the program less than a month. It's ok to buy a few but don't hang onto them like I did. They stop participating or they only accept smaller amount coupons. It will take me years to use up $4000 since there's not much around where I live.
