I received a 4 page advertisement in the mail. It says get up to $50.00 back on your advantage multi for dogs purchase. I purchase two 6 packs of the same product for a full year of coverage for my dog. I send my receipt and the advantage box tops. Just as instructed. I mail to Advantage Multi $20/50 rebate (I sent 2 for the $50.00.
P O Box 410300 Dept AM11192, El Paso, Tx 88541-0300. I mailed February 3, 2011. I have not received my 50. yet. I have a friend who did the same and he has not received his 50. I have my receipt for the advantage and the paper they sent to me. I can make a picture of that if I need it.
