Sorry for breaking Transmute, dudes

Um, obviously law shit isn't the same in holland as in the USA, but over here it works like this. If an article (in a regular store, so I guess it goes for an online store, too) is mispriced, the seller is required to sell it at the listed (lower) price if the difference with the actual price is <10%.
I once checked this because I worked parttime in a computer store. If our computer (and our advertismenets, for example) listed a graphics card at 100 euro, and some jackass in the back stickered it for 90, then we're basically screwed and forced to sell it at 90 if the customer desires such. If he stickered it at 50, we can say 'sorry thanks no deal' like what happened with the transmutes.
In short: if it were a Dutch store, if they have it listed at >3,30 now, they're in the clear.
