GR_LTS is walk-in centres rather than drive-through centres I think

I think @wywywywy is probably right. walk-in centers do not appear as a choice for young children.

When making the script I collected those IDs by combining the responses from the "drive in" option and the "walk in" option. With the result being that the script will fire for both. My understanding is this: ("GR_RTS", "GR_STS")=Both drive through, not sure of diff. "GR_MTU"=Mobile drive through unit, "GR_LTS"=Walk-in unit.

Thanks to the magic of this script, I managed to book a test for my daughter on Sunday. But it's Friday now and we still haven't received the results 🙄

And test just came back negative 😁😁

And test just came back negative

Yay! My daughters did too.

I keep thinking we should turn this script into a live website with current and historic availability.

Thanks for this. We finally managed to get through but the nearest centre is in mid wales.

My wife tells me that PCR tests should cost pennies as there are 384 well machines. They could do 170 tests per run (4 hours).
Factor in the £10/hour postdoc to run it...

Someone is making a lot of money by rationing the tests.
