Prolly in the hundreds - my local B&M lets you taste test as you wish, and sometimes I just go in there with a RDA and spare cotton and spend an hour or so on quiet days just chatting with the staff and tasting, tasting, tasting
Think House of Liquid El Toro range, some of Black Note, Red Vape Reserva Havano Gold and the dark one, and Shade and Dark from Liquid Core. All grrrreat to pretty good.
Latest love (as in 'luuurrrve'....) is Manabush Chiricahua (my tastebuds fell over) , so am working my way through their range...
Abject Failures: Purity Longhorn (throw-up stuff) and a couple from the French Liquideo - all taste of honey (supposed to be tabac). Don' wanna vape honey! Vampire Vape Parma Violets was nice. But not as a vape. Eat. Yesssss......
