Two day shipping? That sounds amazing.
In New Zealand it can easily take 2 months for packages to arrive from overseas, if at all. In Taiwan I could buy locally-produced electronics and had it delivered in less than a week, and I thought myself lucky - but overseas packages got lost twice (maybe 10% of the time) due to not having a Chinese address written on them.
The long shipping times, combined with moving house periodically to keep a low rent, mean my buying habits usually involve splurging on $$$ of online shopping once a year or two.
Asking girlfriend/parents to forward parcels from Taiwan/France delays it even more. I'm still waiting for my Christmas 2020 present: "Oh, I'll just put something else in!" Friends have been even worse: some belt clip cases would only ship to the US, and a friend there still hasn't sent them on (after buying them in 2014). Similar story with a magnetic iPhone cable from Korea (2016). I've basically given up on ever getting those parcels.
Also import fees are all over the place: on Amazon, a Sabrent Rocket Q 8TB SSD costs $1399 + $992 fees (USD) to ship to NZ. The price to Australia is $1399 + $216 fees. I could fly to Brisbane and back for cheaper than that!
Some products (e.g. MacBook Pro A1494 battery for A1398) can't even be shipped at all: OWC and iFixit won't send lithium-ion batteries overseas due to federal regulations. The third-party knockoffs that are available in NZ are faulty, and broke my logic board. Trying to get a new battery is an ongoing struggle for me, and has been since I noticed the swelling in September 2020. I can only dream of the convenience of 2 day shipping.
