It is no wonder that some families return their fur babies sighting the cost of food for them. Today I bought dog food $79.99 Canadian. GST $4 PST $5.60 that is nearly $10 in taxes on top of the price of the food. Luckily I had a $5 coupon or else the cost would be $89.59. I am very fortunate that I can afford that, they have now started pet food banks here which I think is a great idea.
