Items/Shops pricing

[X404]

I'm working on a map for War 3 with a new economy system.
I wondered:
Can I make a shop sell (potion) for (100 gold)
and make a second shop sell (potion) for (300 gold)
Th exact same item for a different price?
And the other way around, Like I buy (potion) for (100 gold)
and sell it to a different shop for (300 gold)?
Please tell me wether or not there's a simple
way to do this that is escaping me.
EDIT:
Then is there a way to make a shop not buy a specific item?
like sell one but not buy it back, but buy other things?

You create two versions of the same item, and make Shop 1 sell the first one, and Shop 2 sell the second one with a higher price. There's no way to modify item price with triggers, unless you manage the item prices with triggers.

To do the sell thing, you'll have to trigger the buy/sell thing.

It's easy. You can check if the item has been pawned at a shop, and add the respective gold depending on the item sold and the shop.

It's all about copying same item, and change its price lol.
Basically, you have a copy of the original item.
The copied ones, you should edit the price
