Costco is offering Covid-19 Saliva test kit by azova.

Costco covid-19, coronavirus test kit

This is a saliva test – not a dreading nasal swab.
They are priced at $129.99 and $139.99. The $139.99 kit contains Video Observation for travelers (I don’t know exactly what that means).

This requires you to follow instruction.

• It sounds like you need to register at Azova.com and complete an assessment. Only after that, you may receive a test kit at your address.
• Avoid collecting saliva over the weekend for the shipping delays.
• After spitting a large quantity into a tube. Pack up your sample and take it to the UPS store.
• Results will be available online in a few days after they receive your package.
• This item is FSA eligible.
