Stacking help please

I'm new to this and need some clarification please. I have huggies coupons I'd love to stack but don't think I can. First, the smart source ones say on them "limit one coupon per purchase". Does this mean, only one coupon, no stacking, no others can be used with it? Or, just only one of this particular coupon but may be combined with others?

I have another huggies that has a different UPC that says the same thing and directs you to comment up top "do not double". Is this just saying they can't double on double days or don't stack? Since it also says one coupon per purchase I m thinking no stacking??

One has UPC 49096008 and the other 49096242

Thanks

Also, I have coupons that say not valid with any other offers so guess I can't stack them?? Seems like I can't stack anything lol

Still hoping for an answer lol. Help

At London Drugs you can stack them as long as they don't say "can't be combined with any other coupon". As for the "limit one coupon per purchase" you can only use one of those coupons in that stack. If you are buying two packs of diapers, you can use two of those coupons, one per stack. I think the cannot double thing just means you can't double the value of that particular coupon. Hope this all makes sense, lol. I just stacked at the Langley LD today with no problems :)

Thanks! So the limit one coupon per purchase can be stacked with other UPC codes. Nice

Just looked thru my coupons hoping to find stackables but only found one. They all say not to combine with other offers or I don't have one to stack with. Sucks
