Apple release day usually also has Chinese resellers in the queue since the device is less expensive in Japan https://www.theverge.com/tech/2018/9...n-china-russia Sometimes Chinese customers prefer to buy from overseas in fear of counterfeits or some luxury symbol? There was counterfeit baby formula in China and I believe Costco vitamins are a popular souvenir/import for price & quality.

I'm not sure how this can be curbed with the current airport layouts. Perhaps duty-free shops should create staffed designated re-packing area public & airside, like a "lounge" for re-packing, and give such buyers a "lounge pass"? Donki & the large camera shops used to offer free store->airport delivery for large tax free purchases. Perhaps these stores need to up their packaging game to remove the unnecessary bulk & pack it in a suitcase instead of a box?
