Stick in a Box
I needed a seamless option for running subscription payments on my site, that wasn't going to kill my margins. I was reading bad review after bad review of existing options and was considering ditching my Shopify store altogether.
I didn't catch Charge Rabbit the first time around, but I did the second — and I'm glad I did.
They're extremely responsive to everything I need, answering emails within minutes. The product has continued to improve each month and it's totally affordable.
