1D III error 99

[Joel Eade]

That's the spirit!!!

You may have some way through Ebay to get your money back if the item is not in the condition as advertised. If that's the case I would message the seller first and ask for a refund and ship it back to them if they will refund you. If not you can get Ebay involved and perhaps reach a resolution.

I have purchased used items ( including a 1D III) from Adorama in the past with zero issues ... unbeatable customer service

The original 1DX bodies should be a good bargain at this point
