This happens in our store all the time, and it is a pain in the you know what! When this happens, although the pending charges fall off eventually, it still creates a negative buying experience for the customer. And we have to take the time to explain it to him. According to our customers, our site is the only time they have experienced this. And I have also never experienced this when shopping online.
So am I safe in assuming that the only way to avoid this happening is by turning off the zip code verification? And doesn’t that open us up to fraud?
