I have ran out of several paints and was off to buy them, but the question is that with Brexit, buying from UK has become more expensive and troublesome (some suppliers are not shipping anymore). Furthermore, I see how brands like Citadel are every day providing less quality, for higher prices (how I would like to buy the Games Workshop from 1999, that had excellent coverage and vibrant colours!).
For me, coverage is first, and vibrancy of colours is second. Other factors are less important, but I always paint with brush.
Hence, I was interested which brands do you use, and where do you buy them. I imagine most collectors nowadays buy them online, with the current pandemic and all.
