It's a very large outlay to purchase satchels 100 at a time amd likely out of the reach of your average mum and pop seller.
It's extra work to have to manually upload the tracking numbers while the eBay system does it automatically for you.
For my items 90% go as large letters, it would take me at least two years to use 100 satchels, just to save 10%, whereas I can get that discount with eBay labels every time, one at a time.
