OK I was the one that originally started this thread about the Purex. Well, I did email corporate and the store manager called me today and basically told me what you guys have all been saying. That the lady should have given me my full amount back (since the 6.99 item was free) plus my 2.00 coupon. So he told me to bring in my receipt tomorrow and he will refund me the full price of both detergents and I get to keep them. They totally reedeemed themselves

This story has a happy ending after all.........
