I see what you mean and I agree with you.  Frankly, after looking through the readme's for these products I wouldn't buy any of them without texture sizes, and that's from the eyes of a texture creator.  I always list the texture sizes of every texture used.  I think it's only fair to my buyers that they're able to know what they're getting before they purchase.  This may be the reason I've never had to give a refund.
