According to the Brita Facebook page they are NOT honoring the MIR that they have had posted. They have offered NO explanation as to why and I can’t even begin to speculate. I am not sure how they think they are going to get away with this but I will keep you updated with any information.
The offer SAYS expires 03/31/2012
Here are some options:
RETURN your pitcher
COMMENT on their Facebook page
CALL and ask for your receipt to be returned to you so you can return it
If you return it to Walmart without your receipt, you will likely end up with a $9.99 gift card, or whatever you paid for it. You should be able to get your money back.
