I am wondering if purchases with a foreign card are still benefitting of a chargeback. VISA's page on the subject hasn't been updated, so it should still be on.
Yesterday, I was browsing shops on Av. Córdoba in Villa Crespo where the outlets are, and one shop advertised "compramos el dolar a $1400". A real deal, but unfortunately I don't think it is going to work long term for me (evil plan: go in there and buy the cheapest item with a 100 USD bill)
Regardless, with the blue and the official rates so close, if using a US credit card with chargebacks it is now worth paying with a foreign card. Mine gives 3% on certain items (food, travel, accommodation, certain shops)
Someone did the calculations and tests for me: https://secretsofbuenosaires.com/tourist-card-p…llar-blue-rate/
Caveat #1: small shops won't accept a foreign card, let alone a foreign credit card.
Caveat #2: make sure the charge is processed in ARS and not in USD.
