price matching and stacking

hey guyss...
i need some help... i am very confused about "stacking" and "price matching"

ok.. what is stacking?
from what i know is that 1 ccoupon can be a printout and 1 a p&g coupon..
but arn't they both magnafacture coupons??? n i heard we cant use more then 1 magnafacture coupon on stacking ?? correct???:shrug:

and price matching is only allowed on products that are showen on the same weeek flyer and different stores rite??

can we pricematch somthing which is on sale in one store and then PM it in WM when its on reg price???? n when its no in that weeks flyer??


someone clear things out plzzzzzzz:icon_scratch:

and what stores allow stacking ??

Stacking is only allowed in the west at Save on Foods and London Drugs. Basically you can combine as many coupons as you want as long as all the UPCs are different and they don't have any wording prohibiting this (ex. "not to be combined with any other COUPON offer" or the restrictive wording on the Brandsampler coupons).

When you price match it has to be the EXACT product as the one advertised on the flyer within the time period you are buying it.
