Hi all, I am just starting out to print labels through Shipstation. I am choosing
USPS ground advantage. I tried choosing the package type of bubble mailer or
flat envelope but it tells me that is an "invalid type". What are you
all using as a package type? Thanks.
You aren't going to use the "flats" option for pretty much anything
(unless you want to for books) because it doesn't have tracking. Even a bubble
mailer isn't a flat.
weigh and measure you parcel (bubble mailers would be 1" or more) and then
it will give you your options from there.
