Options are as follows:
Local:
Officially licensed stores such as Mac Station: iPhone SE (2022): 908K ARS, iPhone 12: 1,000,800 ARS, or iPhone 14: 1.829 Million
Mercado Libre: iPhone SE (2022): 700K ARS, iPhone 12: 840K ARS, or iPhone 14: 984K (you can probably get these cheaper by contracting the seller directly and offering cash payment in ARS or USD without needing a factura)
Shipping:
Aerobox: Within 7-10 days, you buy from the Apple Store, then pay the taxes+shipping. For the 14 base for example, total is is 699 USD + Miami-Dade Sales Taxes of 8.25% ($756.66) + shipping and taxes of 198K ARS.
Grabr: Depends on availability, a person traveling to Argentine buys the item you want, and you pay Grabr via the platform and it basically holds the money in escrow until you confirm you've received the purchase. Their website states about a 10%-20% fee of the base item's total on average, plus any sales tax where the item is purchased. i.e. an iPhone 14 would be $756.66 USD after tax + a Grabr fee of ~$104.85 USD if we assume a 15% cut.
