Hello @AmysCountryCandles ,
The Nift integration provides a great way to engage and re-engage customers, and entice them with gift cards to non-competing businesses as a way of thanking them for purchasing from yours. I'd recommend checking out Nift's FAQ for additional details on how their system and cards work. If you have any specific questions about the integration not covered by the FAQ, or about our partnership with them in general, feel free to let us know and we'll be happy to assist.
Hopefully some other Community members will be able to chime in with feedback regarding how they've used Nift, how they've felt about it, and if they'd recommend it.
