>>8471821They're not and here's proof. Same exact product, both from japan, both images taken at the same time. Both use DHL, but Amazon Japan's shipping cost is literally over 3 times cheaper than 1999.
Amiami, like
>>8471835 said also offers lower prices though I can't easily get a quote on them like on 1999 so its more difficult to directly prove. Remember that 1999 previously did not offer DHL until EMS and SAL got murdered by covid, so they had to hastily negotiate a deal to handle their shipments. And DHL is overburdened with work because of the shutdown of so many international shipping systems, so they likely weren't willing to cut any deals right now. The result is that 1999 shipping is as expensive as if you were sending it yourself, while other companies are demonstrably cheaper.
