UPDATE: I guess it was a glitch as the old antidote is back in the shop now.
I was trying to save some money for LE, but looks like they are going to drain us with Antidote 1st. I think will only buy the pieces I absolutely love because then LE will come out and I will be broke. haha.
Also it looks like the last collection at least is now sellable!
