Well, when I was doing this, a nice cashier told me that if I had 6 doublers with different numbers on them they will work all together! 6 at once!
This is HOT! HOT! HOT!
So from then on I was able to do transactions with 6 doublers each time. It saved soo much time.
The Wednesday-Tuesday weekly ad had a set of doublers in it that had the numbers 1,2 and 3. The special Weekend doubler ad had a set of doublers in it that had the numbers 5, 6 & 7! So they work together.
Disclaimer: This is a “Your Store May Vary” kind of deal..as the doublers read “Llimit 3 doublers per family per shopping trip.” But I had great luck with this at 2 stores! Woo Hoo! This will be great to know for future doubler trips.
