I have two 6-pack boxes (12 doses total) of Bayer Advantage II flea and lice treatment for dogs over 55 lbs. Both boxes are new, unopened. Currently retailing for $66.98 per box at 1-800-PetMeds. I'll sell them for $55 per box, or buy both boxes for $100. (Note this treatment is not effective against ticks... just fleas and lice... but if you already use some other tick treatment, this is a good way to treat for fleas and lice.)
I live in Hanover, work in Norwich, can meet you in either town.
