You can now buy an at-home coronavirus test from Walmart's website for as little as $99

• Both Walmart and Sam's Club are now selling at-home coronavirus tests online.
• Buying the test is a three-part process, but customers can get their results in as little as 24-48 hours after a lab receives a test.
• Walmart has also opened 600 test sites across the country since the beginning of the pandemic.

Getting a coronavirus test from the comfort of your own home is now as easy as ordering one online from Sam's Club or its parent company, Walmart.

The at-home tests, which start at $99 and go up to $135, vary in their abilities and testing methods, according to a press release. Some require the more common nasal swab or saliva test, and others can also check for the flu.

The steps to order a test are relatively simple:

1. Buy a code that allows access to a health survey
2. This generates a physician's order
3. Complete test purchase

The tests have been FDA approved and consumers in some cases can get their results within 48 hours of the lab getting the test. Some of the kits will even allow customers to receive a telehealth call if the test is positive.
