I wouldn't commission from them.. not now that is. Seems they can't do anything right at the moment and even seems like they're just 'stealing' money. I commissioned from them in February (just some Rinoa deluxe duster fabric so no costume had to be made). I still haven't gotten anything but we payed them in February (you can't say they're delayed because the costume isn't finished, so something is definitely fishy).
Anyway don't count on paypal to help you, they only have a short period of time in which you can enter a complaint. Call your bank, they usually have a 3 month policy. I called them three weeks ago and got a call yesterday that they're paying everything back *phew*. So I would stop waiting for your package to arrive and try to get your money back asap.
I'm never going to buy something from them again, definitely.
