Samples cost $6. I bought 5 I thought I'd like to try out. The two flavors I didn't like ended up costing me $12 total. Not pennies, but it didn't exactly bankrupt me either.
If there's one or two flavors I don't think I'd like in a sample pack, I'd buy it anyway as maybe I'll actually end up liking them. Didn't think I'd care much for Tiki Juice, it became my favorite flavor; thought I'd really like Tribecca, but I don't care much for it.
Descriptions of how something tastes aren't very reliable in my experience. It's not just vaping - beer, cigars and food too. I've had too many not so good micro brews to put stock in people's opinions. I've also found excellent micro brews that people either raved about or hated.
Taste is a roll of the dice.
When I first ordered my G6 kit I picked Turkish Tobacco and ordered some prefilled Belgian Cocoa cartos too. Loved both flavors. I've since ordered the Tobacco and Gourmet Sample kits. Got some LR cartos and a mini-tank in each color. Been sampling away. Turkish and Belgian are still favorites.
Wasn't sure about Tribeca but it turned out to be my second fave out of the Tobacco sampler! Midnight Apple surprised me enough I'll have to sample again. Prime 15; I can see why so many like it. The flavor is not too amped up so it'd be good to vape all day if you do that. But I find it a bit....boring. Disappointed with Longhorn. Torque56 while undeniably good and and well conceived is not for me.
Malibu, wow! So many raves but I didn't think I'd like it as much as I do! And I thought I'd like Café Mocha but....no.
Have yet to try Twisted Java and Shamrock. If Twisted has the same coffee base as Café Mocha it'll probably be a pass. If Shamrock is like Belgian with mint probably a go.
After some big bottle purchases of some of the one's I like, I'll probably try the Menthol Sample pack. It'll be educational if not fun and tasty.
One last thing. None of the flavors are so bad that they couldn't be used for just a nic fix (well... except maybe Café Mocha. Kinda reminds me of buttered popcorn and I pretty sure someone else on this forum posted the same.

). And that just reaffirms that the ones you like, you really do like before you invest in a 30ml.
