Can I ship clothing in a plastic bag?
Can I ship clothing in a plastic bag? For new shirts, slip into a plastic bag and slide the package into a poly mailer, a secure and lightweight choice of packaging for small items of clothing. If you're sending multiple shirts, it is advised to use a box.
Is it cheaper to ship with your own packaging?
As we mentioned above, combining your own custom packaging with the right USPS service is often more cost-effective than using flat-rate boxes. One such option is taking advantage of cubic pricing. Priority Mail cubic pricing is a more efficient USPS service for shipping small packages that weigh up to 20 pounds.
