EXPIRED COUPONS AT CVS

When I was doing my CVS run today, I stopped in at the location by Cobblestone. I was told by the cashier that they took their ECB's for two weeks past expiration (the beach takes one month past) and they also take manufacturers coupons for two weeks past expiration also! She did have to tell me that! Now I am going to have to scour deals to see what I can put together with expired coupons!
