Rainbow double coupon days

Have you tried doing double coupon days at Rainbow? I've recently started, and have learned how to get the most for my money. What double coupons days means is that if you spend $25 in the store on anything, then you can double up to 5 coupons- up to $1 but no more than that. One thing to keep your total as low as possible is to know the way the register works. To reach $25, it counts the shelf price of a product. Here is an example.

This week, Folgers coffee is on sale for $4.99- the BIG tub. That is a rock-bottom price. That alone is a good reason to buy this because there are coupons from 11/8 RP insert. If you double it, then the coffee is only $2.99. But, keep in mind that this coffee's shelf price when not on sale is around $9.99. This will make it really easy to reach your $25 total.

Here is what I plan on doing today:

Buy 3 air wick freshmatics kits for $4.99
-use the $5 MQ from 11/15 SS
Final price: free

That will bring my total up to $15 (at a minimum), without having to pay for anything. Sometimes, rainbow makes the shelf price the sale price. (Tricky Rainbow)

Folgers coffee: $4.99
-Use $1 MQ (doubled)
Final price: $2.99

My total spent at Rainbow should now be at $25......so here is what I will get free after coupons (same transaction)

Ragu Pasta Sauce (2): .87 (on sale through today only)
Buy 2 and use $0.75/2 coupon from 11/15 RP
Final price: .24 after doubled coupon

Nabisco Triscuit, Wheat Thins or Chicken in a Biskit $2.00 (3)
Use $1.00/1 coupon from 11/8 Smartsource insert
Final price: Free after doubled coupon

So, my total OOP should be about $3.25, and I will get: 2 Ragu pasta sauces, 4 Air wick kits, one tub of coffee and three boxes of triscuits. Not bad!
