Cheapest way to ship large packages?

Hi everyone,

I would like to sell some homemade furniture, like tables, chair etc. online, domestically in Japan. Looking to do some small business. What would be the cheapest way to it have them shipped?

For example, the dimensions of a package for a table would look something like this:
140 x 70 x 50 CM

Thank you so much in advance.

pack it by yourself.
call yamato transport to pick up, or bring it to their branch.
write a shipping label.
pay money.

Thanks but it would cost more than 10000 yen just to ship a package, according to their website.

The shipping fee would cost more than the item fee itself.

Any more suggestions for cheap methods?
