I wouldn't call what you're looking for a sample pack, that's more like a specific detailed order. I've been
vaping 18mg juice from a B&M of unknown PG/VG ratio, and I too want to find out the vapor differences of varying strength and ratios, to see what I enjoy most. But I've decided to go the DIY route, instead of paying top dollar for small bottles. I did the math on what I've been thru for juice thus far at the B&M, and after 2 months I spent $58 on 75 mL. It was spread out thru 13 small bottles, and most had a little extra juice in them so maybe I got 80-90 mL, but it's still so much more expensive than making it yourself. I just spent $42 on my 1st DIY order, and that's gonna allow me to make about 350 mL of ~20mg juice, w/ 11 bottles of flavoring to play around with. I'm gonna experiment w/ varying PG-VG ratios, and I'm gonna make a small bottle w/ high-strength nic. to see how that vapes. When you're buying 5-10 mL's of premade juice you're getting the worst deal price-wise, and I'm definitely gonna be saving money, on top how cheap
vaping already is. But more importantly, I can start doing some creating & experimenting.
