On a certain payment page, Mullvad gives a code that needs to be put in an envelope with the cash, so they know what account to give the time to. If that page is refreshed, I believe the code changes to something else. Is the original code from before the page was refreshed still valid too though?
So if someone wanted to split their payment into 2 or 3 envelopes they drop off at different locations, in case something happens to 1 envelope, could they refresh the page several times and collect a code for each envelope, or would only the latest code they see be valid?
And out of curiousity, how long does each code remain valid?
