A 25 pound package going to puerto rico.is there difference in cost if we box it and rap it ourselves?

I gotta return a package with Amazon I got my labels and an old box can I drop packages at this location?

You don't have to pay for the box or the tape but other than that you still have to pay for shipping

It will cost more if you purchase shipping supplies from UPS but, make sure whatever is being shipped is packed correctly or you may have to repack again when you get ready to send.

If you buy the box from the customer counter it will add yo the cost of the total shipping transaction.

No
