can I top up the difference to enjoy the Buy 2 get 1 Free? In the first place, you did not indicate that I have to buy the x 3 (+$7.20) x 2 to enjoy buy 2 get 1 free. So buying 2 (single bottles) and get 1 free , I actually paying more per bottle basis. So now, I'm suggesting to top up the difference and you ship me the other 5 bottles. I think is quite fair. Please advise.
