I bought a few extras to trade in the distant future at the advice of the members here. I figured that most of those "rare" alox colours used to be available at affordable prices many years ago. By keeping these blue, olive, copper aloxes for awhile, I suppose I might be able to trade them for 2 of the current alox models at that time. Even if my calculations are wrong, I should still be able to get back what I paid for them.
As for the flippers on ebay now, you can see that they are slowly lowering their asking prices to around $70 but still no takers. When the 2nd batch of the same colours are released by Jeff, prices should come crashing down further
