Thanks for the story.  My legs are still cramped, but I suppose it was worth it.  You are concerned for other customers of Coinabul who might get a refund only of the price of gold, but Coinabul would keep all the other extra expenses.  If you're right, that is a black mark against the company.  It would be nice if others showed up to let us know either way.

I don't believe Coinabul is prohibited by law from sending you 90 BTC.  They are most likely prevented from that by not having bitcoin, but that is a problem they ought to solve.  They ought to change that in their terms of service: "Coinabul will keep your payment until we know that you have what you purchased.  If you request a refund, we will deduct the cost of our expenses and return the rest of your payment in kind.  If we are unable to ship your product, we will return your entire payment in kind.

If that's illegal, then I think the moral thing to do is break the law.  If they want to mitigate exchange rate risk, then their bitcoin prices can be higher.  They could offer the lower price to customers who agree to be reimbursed in fiat at Coinabul's discretion (which is what bravenec did, assuming he read and understood the TOS).  This only means that I wouldn't recommend using them until they make some changes.

If you read Lysander Spooner's excellent book on the history of the Trial By Jury (that's the title too), you will see that the institution of the Trial by Jury is a direct and millenia-old result of bad law.  Martin Luther King, in his famous "Letter from the Birmingham Jail," called on all Americans to actively but peacefully oppose laws that were morally wrong. Every thoughtful person knows that this is true.

I am anticipating a boom in businesses who openly declare that they are aware of unjust laws and will actively disobey them for the good of their customers and the rest of society.  Consider this post as my own such declaration.  With SOPA and PIPA like legislation crawling around the cesspool in the US capitol, I'm looking for ISPs that will make this declaration.

Oops!  I got off topic there, didn't I?  Was it worth it?
