yeah me too, I would buy a bottle of Oriental Plunder concentrate tomorrow. I think with things as they are there's no downside to having concentrates, years back I could see why companies wouldn't want to do it. ... but now, it's just an extra market. There must be a fair amount of people like us who just don't really buy made liquid any more.
The mixing percentage is a big thing for me though, I have a one shot here that mixes at 20%, that's 12ml to make a 60ml bottle.. when the concentrate comes in a 30ml bottle, that kind of annoys me, I make a couple of 60ml bottles with it and it's almost all gone. By the time you add VG and PG (and use your own bottles) it's not saving much over just buying 60ml short-fill bottles and just adding the nic.
They need to be down at 10 or 12% max for them to seem like a good buy to me.
@Digbys ... if that's even possible.
