I agree with you.

Several people have already voiced this opinion, too, a couple weeks back.

I believe that these short term sales are mainly designed as attention-getters for the vendor and his products.

I bought one product that way, and I was grateful for the discount as I wouldn't have paid retail or even the periodic sale price for it. But I missed the window on another one, so it's now on my wishlist (which is maybe what they really want to achieve, LOL).
