1. Fatty you said yourself. You make money on the add on sales, but if you beleive for a minute the pet crowd does not shop around your nuts. I can tell you right now every person that comes into my store knows what the price an item is somewhere else. A lady just today walked in and said "At Walmart a 10gal. tank set up is 29.95. Who much is yours?". (I did make the sale by the way without giveing a discount.) If you raise the price of Pet foods your clients will know. If you lose these people you lose there add on sales. This will hurt Petco if they raise prices. 2. What nut takes a cat from an adoption and spends $2500 and blams someone else for your spending. I'll get you a cat and pay for it's first check up and anything that needs done to it at the time. This will only cost you $1250 up front. Thank of it as a half pried cat.
