Amiami is another online just like HLJ. To be honest, I prefer to use amiami due to the price. Same as HLJ, place order and select shipping. Once it is ready, they will send you an email asking you to pay before shipping it to you. Their processing time is much faster than HLJ in my opinion. Sometime it can be as fast as a day assuming you order in the morning.
For p-bandai, i use buying service. But that is for p-bandai japan. They don't accept overseas card. Which buying service etc, you have to look up for yourself.
For the HK p-bandai, maybe I will find sometime to shoot them an email to check if they will ship to forwarder like 65daigo assuming they accept overseas card. If not can try their buying service to purchase it. I haven't tried p-bandai hk so maybe you can try and let us know the results
