I'm sorry if it looks stupid.

I've bought a 20 Percent Discount Card and I'm little concerned how to redeem it. When clicking on it, I only have general options, the "other options" being empty. Is there a special link to use it or anything else ?

Thanks.

As far as I remember, you just have to have the card locked in your inventory, and the discount will automatically apply when you buy things from NPC shops (:

if you Lock it in your Inventory, NPC shopkeepers will still be able to see it and it will automatically apply. That's all that needs to happen, there's no "use card for this transaction" button. If you get the bonus main shop discount from restocking and it is still operational, it gets applied first, and then your 20% discount card applies.

Oh ok ! Thanks both of you !

you are welcome.
