Update - just got my first order from TV. I got the butter rum since it was on special this week, and then also some samples of lemon pound cake, peanut butter cookie and tasty finger (butterfinger). Well I just fired up some of the tasty finger since this sample was "born" earliest and had steeped to a nice dark amber brown. Man, you guys did not steer me wrong!!! So freakin good!!!!!
I can't wait to try the others.
I'm a total Tasty Vapor fanboi - I live nearby, so I stop in all the time. Love, love, love their stuff - and they have a "secret" menu you can ask for, if you're nice.

(Older discontinued flavors and custom mixes from customers, etc.) They have offered to custom mix anything I want, they really don't mind, and they know their flavors.
Steeping varies with their flavors, some are good right away, some age slowly, some POP after a period of time.
Tasty Finger I love, but it's a troublesome one for me, most of the time i get chocolate, but the peanut butter is very elusive. It might be me, because I'm trying 5 pawns Grandmaster right now, which is PB and banana, and I'm not getting ANY PB.

This one mellows over time, after a couple of weeks, it's in a good, chocolate place.
The Lemon Pound Cake took a week and a half for me to steep - and it went from good (zesty, lemony) to WOW literally overnight - now it's a mellow lemon and cakey flavor, it's delicious! It's very close to an all day vape for me. I prefer this one in a ProTank, oddly enough.
The Butter Rum is fantastic right away, LOVE that stuff. I've been told it has Bacardi in it, as well.
Alien Blood, I'm vaping right now (Tropical fruit). Alien Blood is another you don't have to wait for, and doesn't change much over time, but it will change at different voltage levels, and on different gear. I do NOT like to drip it, I prefer it in a carto. It's a very refreshing flavor.
Strawberries and Cream is my #1 flavor. It's very strawberry right away, the cream comes out after a while, between 4-5 days. Enjoyable either way. I love this stuff, I need to start getting bigger bottles of it!
I'm waiting for Orange CreamPop to steep right now - it went from a clearish pale orange to a darker orangeish brown the last couple days, and is smelling really good!
Others that I've tried and recommend are Cafe Mocha, Black Licorice, Boston Cream Pie, Tin Box Mint, Tobacco (let this one steep, it's really, really good after two weeks), German Pound Cake, and Pineapple Orange Banana.
The next flavors I want to try are Apple Pie, Irish Cream, and Waffle - someone was vaping that the last time I was there, and it smelled incredible.
