When is the next scheduled clearance sale?

I'm finding that more and more of the items on my wishlist are moving to clearance. I'm still a Poser user, no Daz. That tends to mean nothing genesis. I don't like the Clearance system which puts items on a paltry fixed 30 or 35% off. I never bother to look at them at that price because there are always other equally interesting well-made items I would like to buy that can be had at less cost. I maximize the use of my funds since most of my work is discretionary and not really 'needed.'

I've heard that Prime gets them at 55%, but personally I've never seen that as a Prime member. They always show in the 30-35% range.

I feel the only time I get good value on clearance items is when there is a big sale.
