Not specifically, but some merchandise yu outlive their sale date, got this 'last chance sale' then usually, per many ankos about yukkuri-shop, got recycled as feed or breeding stock in the back of the store to make room for younger(and cuter) baby-yu/koyukkuri in the front/sale display.
It was written, 'pre-disposal, special price', 'last today'.
But reimyu and maricha types are usually used as feed for predator-yu or abyuse-yu anyway.
