Donate any amount you would like to US Health Fairs to help testing for SARS-CoV2 (2019 Novel Coronavirus). Your contribution will be applied to the purchase of testing supplies.
Your CC donation has a 3% transaction cost to the charity. Since you would like US Health Fairs to receive your entire donation, the system is charging you a 3% "TAX" to offset that 3% transaction cost.
This is a fully tax deductible donation. You may use this receipt for your tax records of the charitable donation you made today.
