I've got Instacart credits on a couple of cards also. I never use Instacart but DD does at times. I ignore almost all things like delivery services, Uber, Instacart but maybe I should at least familiarize myself and understand it in the event I need to use.
If these Kohl's credits repeat themselves, I might be tempted to load them and use them in tandem. I've had 3 kohl's offers each time and used all of them, but many are going as gift card xmas presents, plus reloading
Amazon.
I do get a little irritated when I see how much more it costs using these services, but that's probably because I can so easily still shop for myself and I have the time. DD just doesn't consider expense because she is a different generation and also has a good income and few responsibilities.
