UK here. There was a shortage of self-test lateral flow tests a couple of weeks ago, but that's over - they have plenty in stock now. I can go to the NHS website and order a pack of 7 tests, and they'll arrive the next day. They're free. Teachers and medical staff don't even have to order them; they're provided (required) at the place of work. I happen to be signed-up for a survey by the Office of National Statistics; they send someone round every week to get a swab from me for PCR testing. I get the result from that by email, the next day. I have more confidence in the LFT than the PCR test, because some of the PCR test labs have been shown to be dodgy. The ONS is doing PCR tests because the PCR test gives them information about variants, that you don't get from the LFT. The ONS cares about variants and how they are mutating and spreading; I don't. LFT is good enough for me. I'm going to do an LFT right now, because I'm about to attend a family gathering.
