I have two e-liquids flavor I love (LOVE) but they are both very high VG and I'm looking to thin them out a little. I do think the VG is starting to give me some congestion issues. But I just don't want to waste or give up on these flavors I like so much. Anyway...I've only seen a couple of sites selling PG (but I've just started looking). I don't want a huge bottle since I won't be needing a ton of it. I want the best quality I can get. Any suggestions please?
