Hi Mark,
Unfortunately we can't always continue to stock certain liquids depending on what the manufacturers are doing and whether or not they are even in demand from the majority of customers. There are many brands of liquids that we have stocked for many years and continue to do so due to their popularity and availability.
Some unfortunately became unavailable due to changes in legislation (Hometown Hero pulled out of the UK market - Not our choice ) or changes from the manufacturers themselves.
From what I can see are really only two or 3 brands you've chosen with ourselves and one flavour profile stands out which is Lemon Based. Epic Juice being one brand and Vape Monster being another.
Unfortunately these were both simply not doing well enough for us to feasibly justify continuing to invest in stocking their ranges. Not without being a detriment to being able to cater to the majority of our customers. There are however alternatives that have been sourced to replace them. For instance Ohm Brew's 50/50 Lemon Lime Lolly, should be right up your street.
Have you considered trying that out ? If you like I could arrange for a few in a couple of the flavours you seem to have gravitated towards in the past to be sent to you ?
