I might be one of the few but I think Stern store for apparel and collectible sucks. The only thing I look for is the game accessories. To my taste the same old Stern logo for shirt, hoodies is boring. Do I want to pay to have the privilege to advertise your company ? nope. I remember when The Walking dead pinball came out they had different shirts models for the release. I bought 2 different ones.
I would be more into shirt or merch from pinball titles which they paid so much to get the licenses.
Stern pinball Iron Maiden shirt would be cool. Also they should sell different translite models. I always end up buying them on ebay for more because they don't sell a product they make in their store.
To me it's not the price that much, it's the inventory that is lame.
