I spent some time in Argentina last year and discovered the hard way that you must buy your own bags and that the only bags available where I was were canvas. Still, they were only a few pesos and proved durable. No complaints in the shift to bringing your own bag or buying one that is actually useful. The "bag for life" bags in the UK by contrast aren't that great.
