This caught my eye, however:
"A failure to comply cancels the transaction. You can get your money back and keep the goods. If the sale was for a service or a digital download, the contract is cancelled and no further payments are due."
Wow. Seems like it would make a ton of financial sense to go hunting for online shops located in the U.K. that are not complying with this law yet and take advantage of this, helping them learn "the hard way"?
