Hey Jordi , I'm still wondering if a problem showed up with your credit card system. You said it looked up the residential address as well and if you remember 3 different good cards of mine were rejected by your system.

I spoke to the two banks involved and they said there was nothing special needed on my part and in fact I bought some stuff from Adafruit.com without problem with the first card I tried at your store. Its winging its way here now and the blimps I had to let Peter from toysdownunder.com get and I bought them straight from him.

Sorry we could not do business. Hope it works now.
