Beginning August 26th Dollar Tree stores will accept manufacturer coupons.  MUM spotted this statement on the DT Facebook page:

Dollar Tree: We have been testing several markets across the nation over the past year and we are happy to say we now have the ability to accept manufacturer coupons! This will begin on August 26th! There may be an exception to this date for a small selection of stores but all will eventually accept manufacturer coupons.

Hmmm, now I have to add a new category, ’cause I’ve not shopped there in the past!
