went to site got bitcoin amout copied it
it ended in e-5 not sure of the amount now 9.xxxe-5
the amount enter in bitcoin did not have an e-5 and was 600,000 when i clicked on usd.
anyway I tried but maybe if they had sent me a dollar amount I could have ordered it

I realize it is my not understanding bitcoin enough
cnverting what i was sent to usd ended up being 4.27
that might not have come out right and just caused a problem

have the coinbase wallet and chose pay on the left column and then send and copied the amout in btc I was sent
