Bests & Worsts Reviews from Amazon

I purchased my first bottle of this on Oct 2,2019 for $29.99. I really liked how it made me feel and didn't want to run out. I purchased another bottle on Oct 8, 2019 for $32.99. Then today I went to purchase another bottle, my son is taking them too and they really help him. The price has gone up again to $39.99. Really? All this in less than a month. Didn't purchase a 3rd time and will not. It is a good product, but I can't pay more every time I order it. Will look for something else.
