Buy Chinese boxes/cases in Europe.

Hi guys, good evening all, im creating this topic, just to ask for you help and suggestions, about buying Chinese Pokemon TCG stuff, through internet.

1. Those facebook groups about chinese TCG, where some guys do big posts about wholesale, price lists, shipping worldwide, they are legit? They are any person of that Facebook groups, that you suggest and give good feedback?

2.For me, that lives in Europe, Spain, do you suggest anyone that sell chinese stuff, already in europe, to avoid customs taxes??

Thank you all.
