Postage is dependent on Weight, and Measurement of package.
There are also regulations on how the box is sealed.
Best to just take the box to the USPS Counter Clerk, they will print the exact postage, if you can ship it.
You can also use, UPS, FedEx, DHL, etc.

Go to the Post Office..........They will Weigh it, and Print ONE stamp,......You can not " just guess" how much postage to put on

Yes you can use stamps, the amount depends on how much it weighs, no you cannot put packages with stamps in a collection box . Those you have to take to the post office
You can thank the unabomber for that since he mailed his bombs that way
