UGH. I'm having a nightmarish time trying to order something off Rakuten Global. The shop I purchased from has asked me to send payment via paypal, but for whatever reason the language barrier is preventing them from understanding that I have no idea what their paypal address is... Not sure what to do at this point
The handful of times that I have ordered from Rakuten Global, I have always been emailed a paypal invoice a few days after completing the purchase through the checkout. I have never had to pay immediately. It may just be a case of having to wait until they get around to sending it to you.
