There is no difference to my knowledge as long as they use the same master source material, they should perform the same. Most CD's are manufactured in the local country/region. It cost too much to ship and import CD's for what they sell for. It cost nothing to send the master digital code to a local factory.
There are rumors out there that CD club CD's are inferior to the identical store release, but all tests and other attempts to prove it have failed. It makes sense also. I cannot believe Sony, or any commercial record company would allow a CD club to sell an inferior product with the Sony (or other company) label on it. The two biggest CD clubs are owned by BMG and Sony. They just use their own factories to make the other label's CD's.
They mark them "made for BMG club" etc, to keep retail store owners from buying them and reselling them in retail outlets.
