both players must be mastery rank 2 or higher and still have trades available for that day. (It limits you to one trade per day and increases, as your mastery rank progresses).

I don't believe there is a cap on the plat you can pay for a mod, but there is a pretty heavy credit tax the other party will have to pay for each plat you pay (He'll pay 500 credit tax for each plat you pay him). You will also need to pay a credit tax on what you are receiving. In the case of a mod, it would be 2000 for common, 4000 for uncommon and 8000 for rare. I don't believe the fusion level of the mod makes a difference, other than the buyer/seller perceived value.
