After reflecting longer, I'm actually concerned about the prices being listed upfront. I know some people like the transparency, but by the nature of print-on-demand, the prices tend to be a bit higher than what people are expecting (from my experience so far), so there is something good about them having to click on the item to find out what it costs (psychological research demonstrates that the process builds some small level of commitment, and if they really like it they will then be motivated to rationalize the price). If they think it looks expensive before really looking more closely at it, we lose the sale.

Is there any way that shop owners can have the option whether or not to show prices on the product list page?
