So I signed up for Aftership Returns Center - I created a Postmen account connected to USPS.
So in the 'Auto-label generation' settings, one of the things it asks is the Package type (Package, Custom, Soft Pack, etc) and the dimensions. I was testing a shirt & chose Soft Pack & used dimensions that I thought made general sense.... but got an error because I didn't use whatever the actual dimensions for that pkg type were.
Okay - so if I'm not sure WHAT kind of pkg the customer will use (their own box, the bag it was originally delivered in, etc) - and in fact the email notification stipulates they can indeed use their own box.... how should I fill this out?
Should I just select 'Custom' & add reasonable dimensions? Is there a big cost increase for doing so? I'm just not sure how to proceed here?
