DISCOUNTPETDRUGS.COM IS A VERY dishonest, very dishonest business. I paid $106.00, via internet for faulty flee products for my cats and dogs, advantix 20 and advantage 9, all this are Bayer products. NONE of then ever worked (af using them for only 2 weeks!)..discountpetdrugs.com refuses to accept responsibility or even return my money or exchanged the products!, and the same with Bayer...I will never buy any of this products ever again. the guy at the discountpetdrugs was very creepy and rude, and the same with the rude woman at Buyer. BE ALERT about dishonest business AND DON'T BUY THEIR PRODUCTS!. read full review »
