I wouldn't mind helping you out. Shoot me a private message
I will gather a list here for you in the next hour or so and I will add everything to the first post at the bottom. Regarding your question about bullcityvapor. If I have never tried a flavor before, I will buy the smallest bottle they have available. If I have tried a flavor and liked it, and it's not mainly used as a base ingredient, then I will buy a 30ml of it at $4 normally. If I absolutely love a flavor and I can't go a mixing session without it, I will buy a 4oz bottle of it and refill the smaller dripper bottle. Typically all the TPA/TFA concentrates are really inexpensive in bulk. I think their 4ox bottle of TPA strawberry is about $6 I believe, which is just stupid cheap.
Regarding the question about how to clean the glass dripper bottles. I'm sure everyone has their own method of doing it. I first rinse the bottle with warm water to get the leftover juice out meanwhile also sucking some water into the dripper and shaking it and extracting it. I also have one side of my sink barely filled up with soapy water, I'm a Dawn guy and it does awesome. I use the water to flush my bottles, I lay them on their side and gently agitate them so the water is flushing the bottle out. Once I'm done with that, I rinse with again with the tap water to get the soapy water left inside, out. Finally, I use distilled water as the final step to "sterilize" the bottle as best I can, along with the dripper. (Now that you made me think about it, I forgot my sterilization step for cleaning my bottles last go around and I've mixed in them and vaped the juice from them. I honestly haven't noticed a difference, but I wouldn't skip it on purpose)
