Im pretty sure i cant and at my last rope but i thought i'd just ask and make sure anyway.
Is there any way to transfer goods from a PC character to a PS4 character?
using ESO plus or something?
No, there is no way to do that, the character transfer was a one-time, one-way copy of data and ZOS made it very clear there would be no on-going transfer of item/progress/anything between servers.
