Is it moral to request the free government home Covid tests if you can afford to buy them?

I’ve been mulling this over since the program was announced. I realize that tests for purchase are not readily available right now but there will be a lag in receiving the government tests too. If one can afford the $20 or $30 for a pack of two tests, is it fair to get them from the government as well?

Bonus question: I’ve seen a few posts about the USPS sending out free tests if you apply there. This seems to be different from the CDC program. Does anyone know if they are the same?
