We're having a robust airing of views, but before it becomes combative let's remember the thread is about Siege toys availability in Australia.
There really have been some serious problems with stock allocations (Wave 1 being skipped or not sent to major retailers, and only being seen in Toyworlds), and speed at which it has hit shelves. Pre-ordering a special item like Jetfire is actually a sensible move, because we really don't know how many will be allocated but know the demand will be really high.
And I have great sympathies for everyone who goes out on a toy hunt only to have their hopes dashed because its been cleared out, especially if they're in rural areas where stores are limited. Amazon.com and Amazon.com.au are good ports of call for ordering Siege product as well that you might consider Tilarta. It's no guarantee though of quality control, and their returns process can be frustrating. And there's something fun about being able to go to a store, see the product, read the bio, agonise over whether its worth the money, and then take it home that day.
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
