I actually do have a tale of Shiniez Lust and escalating price.
The object of my affection? Organics.
(Ridicule me for my overpriced toy later. There's very little buyable left that I actually want for PLD)
I was on Asura at the time, and the going price was 800k. I had about 500k in the bank, and seals and Imperial Standing. I ground and farmed, not seeming to get any lucky breaks on BCNM drops, but through pure force of will I dragged myself up to 700k.
I checked the price. Someone was selling in Rolanmart for 900k.
I went back to grinding, and got a lucky Khroma Ore drop. There were expenses, of course, but that got me up to 900k after all was said and told.
I went back to Rolanmart. The same guy had raised his price to 1,000,000.
Crap. Back to grinding. No more decent drops, I resorted to straight farming, and eventually scraped together 1,100,000. Hah! There, I anticipated!
Apparently, the Organics not selling from his bazaar for three weeks was an indication of high demand. The price was now 1.2 mil.
There was a happy ending, though. I shouted in Whitegate, and managed to get one for 900k. Yay!
