Yeah literally overnight. I was keeping tabs at manadarake on 3 of them all under 22000 yen. Even one at 20000. Was being cautious because i just bought a 31Kai, 31F hayate and a few other things. Was trying to space it out so i'm not spending so much money at once. The 31s was selling very slowly, didn't figure i had to rush into it. Then suddenly they were all sold, even the more expensive ones.
Panic set in and i started scouring other sites and finally eBay. Managed to find one on eBay for 325. I was annoyed i ended up paying more than i would've if i's jumped on the 20000 yen one. So after the seller said he shipped it, cancels the order and refunds my money. frakk. I knew exactly what was happening. Seller obviously canceled the order to relist it at a higher cost.
Now i'm screwed because i though i had one i abandoned the search. Now the were definitely all gone. I just left shaking my head thinking to myself i should've got one when i had the chance. No chance of getting one now unless they reissue.
