My daughter and I have been ordering from Mt. Baker Vapor for a couple of years now, and we enjoy their eliquids "as is" - no flavor shots. Quite a lot in vaping depends on how you perceive the flavor, with the equipment that you are using.
My daughter and I enjoy eliquids from Mt. Baker Vapor, VaporBomb, The Vapor Room, Ohm's Vapes, Mech Sauce, Black Axis, Seattle Vapors, and Vape Wild. All have a decent selection of flavors, good pricing, reasonable shipping, good turnaround time on shipping, and good customer service.

When I am trying a new vendor, or a new flavor from a trusted vendor, I order eliquids "as is" - without any flavor shots or boosts or whatever the vendor chooses to call additional flavoring. If we like a flavor but think it needs a bit more "oomph", the next order will request a flavor shot or boost. Usually we are satisfied with the original mix, and stick with that for reorders. Please remember, also, that more flavoring is not necessarily a good thing. Too much flavoring can actually "mute" an eliquid. I have seen quite a few posts by people who ordered extra flavoring on their very first order from a vendor, without having first tried the eliquid without any extras, and who were extremely dissatisfied with the eliquids and the vendor. Unless you have already tried the eliquid without any extra flavoring, how can you know if it will need anything extra to please your taste, on your equipment?
Please remember to shake your eliquid before filling or topping off your tank.
