$23.19 for 30ml (and that DIDN'T include a 10% coupon code) only works out to $0.77 a ml, shipping included (regular first-class shipping is only $3.20), so if you're ordering in larger quantities and not using priority mail then it isn't as expensive. Yes, it is pricier than the Chinese stuff, and even some U.S. made juices.
Taste being subjective, there are a lot of loyal Halo vapers willing to pay the price for Halo's juices, vapers who swear by them.
I like some other juices besides Halo as well, but I do like several Halo flavor's A LOT. Halo's flavors are very unique. They don't use regularly available pre-made candy flavorings and free-ware recipes like other sites do, their CHEMIST uses raw materials to make their flavors from the ground up.
Each bottle also has a lot number and 'best by' date printed on it.
I would definitely say that Halo's juices are "top notch". They aren't completely colorless, but they don't have a lot of the unnecessary coloring that a lot of the less expensive juices have, probably because they aren't using store bought candy flavorings.
I really enjoy Menthol Ice, Torque 56, and Tribeca, and don't mind paying their price for them.
I haven't tried Tiki or Malibu Menthol yet, but I really want to.
I think their ECFTEN coupon code for 10% off juices might have expired, or not, or their might be a new coupon code.
Also, shipping for orders over $75 is free.
I didn't find their shipping prices to be unreasonable, but until you update the order with your state and zip code, the total will reflect the taxes owed as if you were purchasing from in state, that might be why you are seeing the extra couple of dollars, putting in that info for a shipping quote will lower the total. Unless of course, you live in New Jersey, then you will have to pay the tax.
Their sampler pack offers a somewhat less expensive way (per ml) to try their flavors compared to buying individual 5ml bottles, unfortunately it only includes their 7 original flavors, and not the 3 new ones. You might try emailing Johnny Blaze and asking him if he would substitute the newer flavors for some of the other ones in a sampler pack. He was willing to make a substitution for me when I bought a couple starter kits from him.
