So this is the first time I have to return an item I've bought on Amazon. Basically I bought some puppy training pads for him, and we bought a smaller sample bag and found out we don't need them (he just shreds them to pieces, won't pee on them!) So I want to return the 150 count box we bought of them.

Well when I go to print the label, it's saying $9.15 will be deducted from my refund because it wasn't a result of their error.

Is this true??? They don't have free returns??
