Adding Reviews to a Carrd Shop

Hallo all!

This is my first post on this site, and out of all the Carrd groups I've seen, this one by far has been the most friendly and useful! I was wondering if anyone knows of a way to add the ability for people to leave reviews, whether it be fully coded or widgets from other sites. I've looked at POWr and Elfsight, but they both have big downsides that I'm skeptical to invest in. I've tried many Google searches and never really find anything outside of those two, and when I do, it's -very- expensive.

If anyone has been able to successfully do this, I'd love to know how and would greatly appreciate it. ♡
