Ordered so we could get the filter fast, but we are waiting and waiting, and waiting. We ordered the filter Jan 31st, it s now the 5th of February, and not date as to when we ll get it!
Also the price shot up with no warning, and they sent me an Email with a $5 off coupon the day after I placed my order!
Site says one thing, receipt said another, and final bill was even higher.
