Oh yes, they're veeeeery slow. Mine is coming through 'Sendle', who are even slower than Australia Post. But that side of things is more on the delivery companies than TLTC. Australia Post has done that same shenanigans a few times this year with various packages from a whole bunch of different shops - not just talking toys, also talking home-wares, bedding, gaming, clothes etc - everywhere is affected, especially where it's a delivery service that picks up from the business directly.
Because Covid's only been around for most of a whole year. It would be really unfair of us to expect a major business to have figured out how to increase their output capacity by now.
