Is this person a maker or just selling you some stuff he had? If its someone just selling you stuff they had laying around, id def file a PayPal claim.
If its a maker, lots of things factor into what may delay an order. Honestly in the realm of Fett, 3 months isnt really much waiting, alot goes into making helmets and armor, and your likely not the only customer this person has. Did the person give you a finish date? Folks have waited much longer for things here. Its pretty normal to wait 6 months for something. That said, i know that info doesnt make you feel any better. My normal suggestion would be to wait it out..but thats assuming i knew the maker/seller had a decent reputation. When makers are in demand they get very busy and sometimes cant get to their e-mails as much as they'd like. Again, it really depends who the person is and if they have any kind of reputation here. If its past the date you were supposed to receive the stuff, and is not a well known seller here, and they are not replying to e-mails......Id suggest a paypal claim if you can still do that. If not, well, there isnt too much you can do unfortunately except hope the stuff does get to you soon.
