The $2.75 fee is per label design submission, not per bag printed. Printing is unlimited after approval.
You are charged again when you:
Upload a new file
Submit a new size or grind (even with the same artwork)
Resubmit after a rejection
Replace an approved label with a new version
You are not charged per order or per bag.
Fix the file before you pay. We cannot skip the fee so you can “test” a draft. See Custom label pricing and Why are custom labels reviewed?
