I did loose $50.00. I am going to try to do a charge back, but the site I went to seems like it set up to prevent that.
Making any purchase off a website will allow you to use the chargeback/dispute feature.
Unless you used a "Donate" button which may well mean you're S.O.L if you didn't pay with a credit card or use a different IP address from normal. (so you could claim unauthorized use)
It wouldn't be fair (probably illegal too) to claim unauthorized use because it's not what happened.
