I keep items in my cart on Amazon, then when there is a price drop I get an alert. Works like a charm.
I had several of the J5M colors in my cart "saved for later," a first, second, and third choice for color and when the price dropped on 2 of them I knew right away since I am on Amazon way too much. Only took a few weeks, though yes if you are in a pinch, you take what you can get.
How do you get an 'alert', unless you constantly check your Amazon Cart?
