They're seldom sold in the shop due to the fact that players buy only enough to use for their recipes and you never get them as drops.
I just think it would be nice, as all the snack recipes in WC call for them, yet no vendor sells them there. It would be nice if free players could craft these, too, considering they can buy the recipes for them. :(
I understand the money end of it, and KI has my debit card info to tap into monthly and then some. But fair is fair. If they can buy the recipes, they should be able to buy everything they need to craft them in the free play area.
Good point - guess I never thought of Free-2-play players as crafters of pet snacks all that much. I know every now and then on my Grand, I buy up a bunch of vials and sell them at the Bazaar for lower levels to buy, but maybe I'm the only one who wastes gold like that. lol
