I had been thinking about trying your product since early December but I'm 99% sure the 4 pack price was 120 ( 60 with the half price) with free shipping. It's now 150 and after the discount it is not eligible for free shipping. I must say this is a little disappointing as it makes this product far less attractive from a value standPoint compared to products that have far more established results.
I understand it may have been too good of a bargain previously but this is a pretty substantial cost increase. Just a little feedback for a prospective customer.
