I once sold my newly recontracted iphone 4 few yrs back to a runner for a hp exporter. When he came over to collect my iphone in an mpv, i was impressed by what he had at the rear, at least 200 pieces of iphone 4...i recall mkt price was at least 1.3k for 16gb back then, so 200 pieces was at least 260k, lol. And that is the average daily volume he handled...with all his transactions in cash..
