Anker has such a huge product portfolio, the chance it overlaps its deepest discounts with your wishlist is a low probability.
I quite like the LC90 so I bought it, lower cost than the deepest discount yet which was in December. I was online refreshing at the moment it came up and it was racing at 1% sold every few seconds, it was gone very quickly. If the Powercore 10000 is deeply discounted ( <$20) I might get one and gift to someone. I also told my UK friends about some of the better offers in UK Prime deals which in some cases are lower prices than USA Prime deals.
So I'm not disappointed, it is what I expected, a random collection which is probably more to do with stock levels by region. Stock levels are as much related to competitors own discount offers.
