No more stacking of P&G coupons at LD?

Apparently P&G has recently sent out a letter to all London drugs saying they can't stack their coupons. No stacking for ALL proctor and gamble products. My usual LD location started implementing this this week, along with limiting price matching to 6, and no stacking printable coupons. This new revelation has got me and my friend flustered so we decided to trek to other LD's if they are doing the same. To my dismay, every customer service counter had the cashier holding up a notice of the new rules...

:( Does your LD still stack p&g coupons??

you havent been able to stack p&g coupons for a LONG time... I'm not sure what store was allowing it but they shouldn't have been.

It is ALL LD's - they will not be stacking Finish or Scrubbing Bubbles products as well as per the manufactures
