For items that aren't quite big enough to warrant their own box and for things that aren't that large and heavy, an easy way to save on shipping is using bubble mailers, which can not only protect an item but can also serve as a very lightweight option for transporting something that requires a bit more protection. Shipping something in a box may not only incur additional fees due to the depth, width and height of the box but sometimes cardboard is much heavier than a simple yet effective bubble mailer. Mailers are often easy to package and seal making the whole shipping process faster.
