Hi Bankfodder.... here is a link to a vidoe...
The credit system is interesting, as is how Kutchenhaus price thier kitchens..... how it was explained to me was you buy hours in a factory..... each cupboard or worktop is given a set time to manufacture. When the kitchen is designed, a time allocation is given, say 8.5 hours..... but you can only buy full hours, so are charged for 9 hours.... so, you can get more things that fill in the 0.5 hour for 'free' or you can drop items to get back to 8 hours.
The appliacnces works in a simialar way. you dont 'buy' them, instead each cupboard or worktop you buy comes with credits. These cradits are used to buy appliances, and be anything you like, ovens, taps, dish washers etc. We had quite a large kitchen done, so had plenty of credits available, so used some on this fridge oponer.... its just a gadget TBH, but put a nice finishing touch!... that is if it ever works!!
