maybe it was Walgreens, but I set up appointment online and after answering the questions I was given a price of $130 and asked how I would pay, so I made another appointment checking that box yes and they didn't ask for payment.
When I applied for mine November 3rd the booking apps didn't define test and go to well, I just went on booking last night and the packages are very defined with price. I think the apps are good to use now.
