I am delighted and have enabled it for my shop. I have had customers come to find me elsewhere (facebook usually, but also my website and email) because of difficulties of payment on Folksy.
I love Paypal, but not everyone does and some people are simply put off, they have made a choice not to sign up to Paypal and don’t necessarily want to make use of the limited number of times you can pay by card as a guest via Paypal. I have family members who won’t touch Paypal with the proverbial barge pole.
All in all, I don’t know how many people haven’t completed a purchase because of this issue, but am willing to believe that it’s more than 1. My view is that I want to make it as easy as securely possible for people to buy from me and I believe widening options to include card payments will help that aim.
