The SmartSource company places coupon machines in grocery stores where you can take a coupon right then and there to save on the item you purchase. These SmartSource coupon machines are often referred to as “blinkies” by most couponers. They get this name because the coupon dispensers usually have a green blinking light designed to attract your attention while walking down the grocery store aisles. Blinkies are usually found directly in front of (or at least nearby) the product for which the coupon is being dispensed is for.
Blinkies are free and you can take as many as you need. The coupons will have an expiration date and can be taken to be used at a later date as long as it is before the coupon has expired (it doesn't have to be used on the date you find it). They also do not need to be used at the store where they are found, but can be used at any store where manufacturer coupons are accepted
While Blinkie coupons are free, there are some basic etiquette rules that you should consider when taking them. If you pull a coupon from the Blinkie machine and decide that you don't want it, there is a slot on top where you can replace it so that someone else can use it. Also, only take the number of coupons that you will actually use. There are a limited number of coupons in each Blinkie coupon machine, so to hoard them. Simply take the number that you believe that you will realistically use.
It is well worthwhile to keep a lookout for Blinkies on each trip to the grocery store you take and they can often get you a good discount when combined with other promotions that are going on.
