Sinde Dealjoy Plus will give extra cashaback,do we have info on the amount of that extra cashabck,or that will be decided later?

And how much will be Dealjoy Plus membership?

You can learn more about Deljoy Plus membership in WP, pages 26 and 27.

Regarding the price, I don't think it's decided yet, so that info is not available in the whitepaper yet.

That's odd. Well, what are the factors that could determine the price in the future.

Public sale has not even started yet and most likely after sale is done team will announce prices.

Does that mean that team does not know how many tokens will be minted yet, so that is why they are waiting with the prices for memberships?

Nope, team already knows how many tokens will be minted you can check the token supply on website, so that is not the reason for this.

Maybe they are just developing the economy surroinding the memberships and that is what is taking so long. Probably focused on initial dev atm.

I agree,that might be the case,as with better developed product it will be eaiser to pitch the idea to potential investors.
