You can get lucky there alot. Distributors carry them. I'd find out who the distributor is for Garts Brothers for instance and take the clubs right from there, take them from DHGate, but always make sure you ask first.
Ask always in your first time with a supplier...
'How old are these clubs, and do they come with certificates?
What is the shelf life like?
And how long have they been on the shelf?'
You will dodge many bullets just by getting your questions answered.
