I bought a cheap duffle bag right near the Retiro Bus Station a couple of years ago. About AR$30-AR$35. An interior wall stitching ripped on the first trip I used it. (Granted I was carrying fairly heavy items.)thomashobbs said:The retiro bus station has some shops at the entrance which sell duffle bags in the 30-50 peso range. You can also go to Once, where it will be a little cheaper. Lots of vendors on Rivadavia and Pueyrredon.
