I don't know German, but it looks like it says there's 461 calories in 100 grams, and each bar is 120 grams, so...about 553 calories as the OP said is right.
Though, seems kind of expensive. Each one is $1.57 USD at current exchange rates, or $38.45 for a package of 30 of them ($1.28 each). Though, may be a moot point. Shipping to the U.S., or to the U.K. for that matter, would likely be very expensive too.
Still, kind of makes me wonder if there might be some sort of local equivalent. Then again, there's always candy bars of various sorts too.
