COVID-19 Test Kits are back in stock at Walmart! I’ve used both of the following brands, and they are equally great! The orange box has one extra step, but it’s still very simple. Results are ready in 15 minutes. Don’t forget to hold on to your box and receipt if you want to be reimbursed by your health insurance. Our insurance form asks for the barcode. All health plans will cover 8 COVID-19 tests per person enrolled in the plan per month. That means a family of four can get 32 tests per month for free!
