> A refurbished iPhone 13 is $300 on amazon

Is this Amazon US? Because even in Ireland, iPhone 16 costs 41% higher than in the US (979 EUR = 1,128 USD in Ireland vs 799 USD in the US).

Half of the difference is likely VAT, which is included in European listings but the similar US sales tax is more often NOT included in listings.

(Some US states have no sales tax, but most do)
