Yes, you can. The trick is that you only BUY a cheap subscription to Netflix with an Argentinean IP address. When the subscription is yours, you pay the same price for it each time, no matter what catalog you're accessing or where you're located. And with a VPN like ExpressVPN (which is the best for Netflix), you can easily access all the catalogs around the world (US, UK, Canada, France, Germany, Australia...).
