I've noticed that several of the internet coupons are starting to say "do not double or triple" on them. When we get double coupons can we use these? I was under the impression that the doubles were like store coupons and could be stacked like any other store coupon + manufactures coupon. I noticed Amy made a comment about some blinkies saying "do not double" during the last sale. I'm confused as to why the manufactures would care if the store was willing to "match" their coupon by doubling it.

I've had them rejected at Albertsons.

I think they're are two ways to look at it....

The coupons that say do not double are generally high value coupons and I believe that is why the manufacturer doe not want them doubled. Often these coupons make things really cheap and they may lose their profit.

But I have also heard it said that its okay because the Albertsons twice value coupons are being doubled by the store not the manufacturer.

 I am not trying to sound cliche but I would say let your consciences be your guide.

Thanks for clearing that up.

Here's my understanding:

Most coupons read "manufacturer" will reimburse you the face value of the coupon plus 8 cents handling. Basically they're saying if a store chooses to double the coupon, the store will "eat" or take a loss on the double.  (If the coupon is for $1.00 and they double it to $2.00 - the store will only get reimbursed for $1.08)

In my experience in CA most coupons will double with no problem if the barcode starts with a 5.  Most blinkies start with a 9 and state "do not double". Honestly, I don't know why a store would double one coupon and not another.  It's their loss either way.  However, I too have heard of stores refusing to double the DND (do not double) coupons.  So, I guess buyer beware.
