What are the cheapest lateral flow "fit to fly" and day 2 tests that people have found?
Simplytestme.co.uk seems to offer £12 tests but only for day 2. Covidtestingdirect.com offers £1 tests but these are PCR and only for day 2, and are only available if you pick up and drop them off in person in Cardiff or London.
Chronomics seem to be the best bet for the "fit to fly" tests, as they offer a various airline discounts - e.g. £17.09 if you book through a
BA link, but no verification you actually have a BA booking

. They offer £15 tests through a
Tui link but for that, they do check you have a Tui booking.
It's really frustrating having to pay these charlatan testing companies, when the tests cost £1 or less at wholesale rates. Of course they've got to pay for postage, administration, VAT etc. but a significant percentage of these sorts of prices must still be pure profit.
