Flat rate boxes from the USPS are typically cheaper than using your own box, but there are a few factors to consider. First, the USPS charges a flat rate for the first item sent in a box, no matter how many items are in the box. If you’re sending a large number of items, it may be cheaper to use your own box and pay for each item individually. Second, the USPS charges a handling fee for each box it ships. This fee can be quite expensive if you’re sending a large number of items, so it’s important to calculate the total cost of shipping beforehand.
Third, the USPS may not deliver your package if it’s too large or heavy for the mail carrier to carry. In these cases, it may be cheaper to use your own box and have the item delivered to your house. Finally, the USPS charges a surcharge for Priority Mail delivery, which can be expensive if you’re sending a large quantity of items. It’s important to consider all of these factors when deciding which option is best for you.
