How to source affordable physical gift cards for my store?

[Plutonyx]

I want to sell physical gift cards (plastic ones not paper) but wanted to know if anyone has sorted any third-party ones as I feel the Shopify ones are a bit pricey just to be giving them away when customers are happy with the free paper ones we provide at the moment. Just trying to add a bit more class to the vouchers coming into the holiday season.

Thanks
