Yay! Yet another one who has discovered the wonders of blended contentrates for DIY! I'm glad you like them both, and I'll definitely give the Doughnut King from CF a try when I place my next order wth OSDIY. I know they have it on their website. As far as the Blue Slush, I have a 16oz. bottle of the OSDIY Blue Raspberry Slush concentrate to get through, so I may hold off on the one from CF.
I wish you continued success with your DIY! It is strange, isn't it, that something
so simple to mix up can taste as great, or many times even better than, those high-priced eliquids? I think you're hooked on them now. Happy to have you join the crowd!
EDIT: I will say that I could vape forever and be perfectly happy using
nothing but OSDIY One Stop Flavors and One Stop Blends. But, I do still also enjoy using CAP, TFA, etc. flavorings to make different recipes, too, that aren't offered by OSDIY, CF, or others. So, maybe don't give up on coming up with your own recipes and/or trying some that others recommend. Keep the CF ones for your "go to" ones in rotation, but maybe add some others as time goes on, too. Of course, you don't
have to, but as the saying goes..."variety is the spice of life". Really though, sometimes my taste buds just need a change every now & then, so I have others to make and vape, too, that I like.
