bobshop (bidorbuy) killing sellers with ridiculous fees

The new R30 shipping is great for buyers but sellers get *****ed even more than they were before. They used to take a percentage of the shipping fee as well as a percentage of the item price, now they take a flat rate of an extra R30 from the sellers account. Will these money hungry vultures never stop? I'm deleting my account after 22 years, they made thousands off me every month. I had enough.
