I know I will be using this coupon, for some reason my 10 year old dog who has never had fleas- keeps getting them!! HELP?!?!?My local Walmart sells the flea and tick shampoo for about $3.98, so you can score some super cheap (and pretty good) shampoo with this coupon! Grab it while you can; it will go quickly! Check this coupon out here (I used 92324), under â€œpetsâ€.
