i only got one set... is there an official statement on how many dji gave out to the shops to spread for us?
seems like one shop is more generous than the other... strange...
Some dealers are hanging onto them and then reselling them out at a profit

(As if any company would do something so underhand - unthinkable)
You SHOULD receive completely free of charge
2 x packs of quick release adapters (2 in each pack so that makes a complete set of 4)
3 x packs of QR props (2 props in each pack - one CW and one CCW) - so that makes 6 props in total. A complete set and two spares.
Hope that clarifies things.
If your dealer is saying no, report them to DJI directly as they not playing ball!
