Posting here for traffic, sorry. I'm just so confused about some aspects of the covid testing. I go to Spain in a few weeks (I have posted before, but still unsure). Should I order the test kits now, one for 2 days before returning to the UK and one for day 2 PCR when I get back. I worry about in case flight gets cancelled and the test kits are non refundable. How late can I safely leave it.
Also anyone know who is reliable and trustworthy. I'm so confused by the whole process.
(Don't think I'll ever travel again tbh. 
Can anyone be kind enough to talk me through the process. I'm just so stressed and worried by it all. Thanks in advance.
