Here in the UK you can get them free from the NHS - is it the same where you are? Have you tried any/would you?

Here’s the NHS links:

The test for people without symptoms of COVID-19 is called a rapid lateral flow test.

This usually involves rubbing a long cotton bud (swab) over your tonsils (or where they would have been) and inside your nose.

The tests can give you a result in 30 minutes. They use a device similar to a pregnancy test and do not need to be sent to a lab.

You can do a rapid test at home or at a rapid lateral flow test site.

If you test positive, you and anyone you live with will need to self-isolate.

Who can get regular rapid tests

Anyone who does not have symptoms can now get regular rapid lateral flow tests to check for COVID-19.
