Can't use vouchers in Galaxy store

[Fordy1001]

Hey guys, I'm having trouble using vouchers on the Galaxy Store app. I have a few vouchers saved on my account but when I try to purchase game or app I get to the checkout to use them but they don't appear. Here's what happens 

1. The vouchers on my account 

2. Going to checkout on a game and clicking 'Use discounts'

3. None of the vouchers appear

What am I missing, are the vouchers for in app purchases only? please help.

When you press them, does it show a code? Copy and paste it into the add coupon section.

There are rules and restrictions on discounts. Read them carefully- as i know some are in app and others aren't

Beyond that point what I would say is contact samsung via smart tutor- should be able to get an answer on device

You'd have to look at the vouchers.
The 50% off one is for in game purchases.
Some games won't be part of the promotion.
You need to read the terms and conditions of the vouchers

I think I understand now, so looking at the terms and conditions of the vouchers they all say 'the voucher can only be used for a single item purchase transaction within the Galaxy Store that applies to Samsung in-app purchase SDK' I'm guessing that's it's for in game items only, I also tested this by downloading a free game and trying to buy an in game item and it suggested me a voucher. Thanks for your help
