I am not sure when this is ending, I just saw it while looking at some things on SL Marketplace.
There is 90 pairs of eyes on sale, I am guessing once the sale it done, they will all be deleted. More than likely because they don't want to migrate all of them when the new listing system hits SLM.
Grab these while you can, I wouldn't sit on it.
Most of the eyes are only L$1.
