extra shop for items - tudoz suggested the idea of a hidden store. Perhaps this is the solution to what to sell there:

Two Competing Curiosity Stores. (Cosmetically) (mindlessmuse11) - good design suggestion

Ability specific items. 4 for each hero. Only visible to them. (nathanieljbrill) -
It seems worth increasing the price and difficulty of obtaining them:

Here's a suggestion for alternative character upgrades (perrin.silveira) - and i have an idea about it:

Also - there is an option to create a certain class system in which Kelvin, Ivy, Dynamo, for example, as doctors, will be able to access certain Items/upgrades. It will also make balancing easier if an item may be too powerful/unnecessary for some characters. This can be done as aspects of the characters. When choosing a hero, he gets the opportunity to buy some items in the store when choosing a "class". This also allows for not only class-wide items, but also character-specific ones and can changes some of his/her abilities.

I'd like to see them hidden in certain variable locations at different times, only selling a set number of items before they have to 'move shop' (i.e. respawn somewhere else later).

Maybe they sell certain items at a discount, but I definitely like the idea of certain item skills being restricted to the store.
