At the Plaza Turisol Exchange house, POP; for USA $. The owner is affiliated with RUSA; he uses RUSA's #s. I think that RUSA was / is offering the same. 37 by 1 Spt. 07? Yes! Yes!
Based on the $US at $33RD (as posted for yesterday in this thread) and the $CDN at $.94US (this morning's rate at Scotiabank in Canada) - the rate should be $31RD. $27RD is terrible.
That's why I always take $US and convert as necessary.
