Is there one for shoppy?
I dont think so, but if there was you can find it before you go create a new product.
You can always check the settings also
I agree with what everyone else is saying.
Try your best to make sure all your accounts work, and the buyer is happy overall with thier accounts.
Also, you should enable the fraud protection, because as you advertise and grow people are so much of cheap fucks to chargeback on a most likely 2 dollar purchase lol
