Query: killer

I want to buy some because we have 2 little dogs in the house and I have used this product and its great. Everyone always wants to know what the good smell is. Unfortunatly I can't find anymore around here to buy so I always go to Amazon. Yes! they have 11 cans and I was going to buy all of them but the shipping was $56.00 come on the cans weigh nothing just can't do it even though the cans are affordable shipping is a killer.
