Did my eyes trick me????? I purchased the R Lipoic from Amazon either last week of October or 1st week of November, the price was still the same at $18something, but now i checked because I wanted to stock as I normally do, to my dismay the price at Amazon is $27.54. Is this correct???

Is there any site where I can buy it for a lower price. This cannot be, a $10 hike!!! i hope i just got it wrong.
