People across the UK have told BBC News they are struggling to access coronavirus tests.
Health Secretary Matt Hancock said last week that no one had to travel more than 75 miles for a test.
Earlier, the BBC said several people were sent hundreds of miles away to be tested for the coronavirus.
Now dozens of people are now reporting they can’t even order cotton.
The Department of Health and Social Care (DHSC) said testing capacity was targeted at the worst-affected areas.
The significant increase in demand for testing has led the government to reduce the number of appointments available in areas with lower prevalence, to prioritize areas with outbreaks.
This in turn causes people applying for tests to be directed to centers that are sometimes hundreds of miles apart.
But last Thursday, Hancock vowed to provide an “immediate” solution to ensure people don’t have to travel more than 75 miles, effective starting last Friday.
A DHSC spokesman said: “We are seeing significant demand for testing, but if you have symptoms we encourage you to get tested.
The virus is already at much lower levels across the UK than it peaked in April, but a study of thousands of people in the UK found cases doubled every seven to eight days, with a notable increase in infections in the north and among young people.
Despite rising cases, the number of patients in the hospital has remained mostly flat at 863.
