"Not valid in conjunction..." question

[scjt2010]

Hi everybody, wondering if anyone knows the answer to this:

I have two Colgate toothbrush coupons for $1 each, they are different UPC's and from different sources (websaver and smartsource). Colgate toothbrushes (the kind my coupons are for) are on sale this week at LD for $1.99, so I know in theory I should be able to stack these coupons.... BUT both of these coupons say "Not valid in conjunction with any other coupon."

I've stacked before when the coupons said something like, Cannot be combined with any other offer, etc. but never seen wording quite like this... ?

TIA for any advice

in short no coupon stacking allowed even if you have differents kinds of coupon for one item..it is the manufacturer restrictions not LD..
