Sales

Hello, I wanted to ask one thing about sales in DbD. In June there will be the anniversary, so all the killers should be 50% off, I think. I wanted to ask, will new killers be discounted too? I wanted to buy Kaneki that will be released in a few days, but I don't know if the discount will be apllied to him too. Also, are the discounts only on auric cells or even on killers purchasable with shards?
