D70: order cancelled - idiots!

Got this email today from Cyberport, where I ordered my D70 + 18-70mm lens 6 days ago:

Sehr geehrter Herr K. ,

Sie haben den Artikel Nikon D70 Kit mit DX 18-70mm Objektiv bei uns bestellt.

Wir haben jetzt vom Hersteller die Information bekommen, dass dieser Artikel nicht mehr lieferbar ist, deswegen mussten wir leider diese Position stornieren. Ich bitte um Ihr Verständnis.

Mit freundlichen Gruessen

What Sven at cyberport is essentially saying is that they cannot deliver the D70 Kit, because their supplier cannot deliver it. That totally sucks! So why did they advertise the product in the first place, why did they inform me that they would deliver my camera in 3 to 7 days? Were they just guessing and/or is that the standard answer they give to their customers when they don't have a clue if and when they have the product.

Of course I am a bit to blame for my gullibility and greed. The price (799 € minus 25€ rebate) was just to great for a big retailer like cyberport, there had to be some catch. And they tagged the product as "approx. delivery 30th June". I had the gut feeling that they would never deliver the goods. And I was right. Could have bought the same kit at computeruniverse.de for 819€, but I just let petty greed get the better of me. Lesson learned.
