Has anybody besides myself have a problem with Walgreens not sending them a rebate? In their Rebate Center booklet for December 2011, they offered a $10 rebate towards the purchase of a Ultrasonic Humidifier. I applied for the rebate online in December 2011 and in January 2012 they sent me a postcard asking for a copy of my receipt which I sent back to them on 02/02/12. I have not received my $10 rebate check. I also did the same thing for my brother and he hasn't received his check either.
