I use my local penznace store quite often for liquids and coils. Staff are generally well educated. As with some jobs you have to learn about certain things and with an ever evolving stock it's not always easy to keep track of brands flavours, what coils for what mods. Especially now as some devices will run multiple coils. Anyway. I find the staff here are good at the job. They're friendly and will go as far as helping you set up new devices should you require. Overall good store.
