I know I have been asked What coupons double? Do they really double? Well I thought we figured it out though we didn't. Today I had to stop at Sunmart to get some items and one of the cashiers and I went through the receipt out of all 14 coupons that was under a $1 we had 6 of them that didn't double. So the manager came over and we spread out the coupons, Read the coupons, Re-read policies, etc. WE came to conclusion all rules we thought has gone out the window...the system will double what it wants. So any hoo on that note the manager has wonderfully taken on this task of figuring out why the system is doing this. After spending about 15min extra with this manager and going through every thing which he was wonderful. He totaled all the coupons that didn't double which came to $4.01, he gave me the amount back. He also informed me he will research things out for me and when he knows something, he will contact me and then I can get it out to you. I do hope this helps you out in the mean time. The only thing we both have agreed on is if the coupons says do not double it will not double that is a guarantee. :)
