I'll have to pick up the lemon sometime. I was debating between the lemon and the Formula K. I went with the peppermint.
I've also heard that the Metilsol is an unusual scent. You either love it or hate it. I've taken a risk and ordered some.
I live in Australia and we don't have any supplier who stocks Myrsol. I know in the States Smallflower is slightly cheaper than Bullgoose but it's cheaper again by half (even with postage) to buy from Spain. Juan at "Gifts and Care" does a great job and also sells plastic bottles (which don't look anywhere near as good but are much cheaper to post- they are good for refills!).
