The voucher redemption for customers is really difficult. When using eGift Cards, after putting in the code and secret key, it's not clear that they need to go to a different part of the screen to choose how much they want to redeem. It's not a good design or experience. There are no prompts or red boxes or anything to assist the customer.
I'm not sure if this is down to the theme or design of the site and if it can be redeveloped by third parties OR if it's just a Neto thing.
