You can choose to change a shipping charge you make (for example, removing first class and choosing priority mail instead).
No one will be charged if you delete the original charge and Atlas.md allows it to go through. That is, unless, USPS has already processed the shipping request.
If that’s the case, you’ll be notified of that inside Atlas.md when you attempt to change the shipping type.
At that point, there isn’t anything we can do to reverse the charge.
