In my experience, I think if your voucher is any like of the two vouchers I've been gifted; your voucher will act like a single payment. Each of the two vouchers that I had was £5.00, however, I couldn't use them as a combined payment as the Samsung payment system only allows 1 voucher at a time to be used during a single transaction. I purchased an in-app bundle for £4.99, you expect there will be a credit of £0.1 in your account as you didn't fully utilize the full value. The next purchase I bought was £1.99 which would mean that I still would have a credit of £3.01. Unfortunately, it used the full value of the voucher as payment. The payment setup for the Galaxy store is not built to hold any credit/balance after using the voucher. It restricts users to fully use the voucher regardless of the value in one single transaction....see attached pictures.
Once the transaction is complete, the voucher will disappear, then you would need to go to Samsung wallet under voucher and you'll find the voucher, it may not look like it's been used but when you try to copy the voucher nr and add it back to the payment it will give you the message that it's not valid. If you look at the t&c of the voucher, the attached picture, only be used for a single in-app purchase.
I might be wrong and there might be a different T&C for your voucher, however, I find it hard to understand how they will prevent the payment system not to use the full value of the voucher and only deduce the transaction amount.
Hope it makes sense?
