Yes, and Amazon is a great solution as they have the distribution network, the nhs does not.
At six pounds you can test more than once, when you start to make it expensive people will test once then think twice about doing it a second time, and many people won’t have spare money.
A small profit, should go back to the nhs to help repay the costs it is now enduring. However without making it unaffordable to those on a low income, the test should be available for all, and a family of four, many don’t have twenty four quid to spare. Never mind two or three times.
Because if you test and you’re negative, you’ve not had it. Are you going to test again if you get ill? People shouldn’t be stopped because of cost, and next day delivery from amazon is a brilliant cost effective solution.
