Gotta like those quick turnaround trades, especially when there are nice profits involved.
Less than 2 hours from buying to selling for an easy 80 million ISK profit. Actually less time than that. I'm not sure exactly how much less but it was definitely less than an hour after I logged in and posted them for sale.
Just goes to show why you should post things for sale at reasonable prices rather than trying to gouge too much. Other Cranes posted for sale in the region were around 150 million (very high compared to prices elsewhere) and have just been sitting for a long time, NOT selling. Yet my 2 posted at a slightly higher than normal but still reasonable price sold very quickly.
