Ok, bold marketing move, imo it should work like 70% off for everybody + plus the percentage off for prime members on clearance items you've decided to give them.

And ask yourself, a store in your city announces a 70% storewide sale, you drive to the store and see that only like 1/3 of their items are at 70% and the others at 35% off. And they tell you, "yes the other items get additional discount only for our VIP customer club members", maybe we should have told you in the announcement ?"

But I'll stop arguing here, I'll simply not buy older items during these "storewide" sales and of course no offense to you.

Btw. : The first time I've asked , they (not you) told me like that it simply wasn't possible to also reduce the "clearance" tagged items atm., but that it will be changed (if I remember it right).
