It's ridiculous that youth-sized shirts on MbA have the same base price and same royalty as adult size shirts.
A blank youth-sized shirt is obviously going to cost less than a blank adult size shirt. The base price and royalty should be adjusted for this, much like the different size pillows are adjusted automatically.
It is difficult to compete with other child and youth shirts on the market at the current prices.
Plus, when we raise the price on the adult shirt, it raises it on the youth as well. (Unless you do separate listings, I suppose.) This means that a shirt that might sell awesome for an adult at $19.95 is not going to sell at ALL for youth sizes because that's just too expensive for a kids shirt.
Please, adjust the youth shirt size base price and royalty structure!
