Thanks very much for the replies.
A few things to clarify. I now find out its not the clipsal 2000 series but it is the Puma range
http://www.gsme.com.au/switches-sockets/cats/puma that he is currently using.
Not that it matters, either way the 2000 series, classic or this puma range will be just fine for the most part.
I cant change builders, we are in too deep for that and I have to say he has been very reasonable and fair for 99% of the time. All the other variations after we did the colour choices/fit out selections were below what we had anticipated ourselves (we did some rough calculations based on retail pricing).
The only two things that has shocked us is this electrical over pricing and we tried to change the house garage door (he quoted double what we could buy one retail) but I since found out he had already ordered the one we originally picked. We didnt pursue it because we are ok with the one we are using.
So, there will be a logical reason he has inflated his prices so much. No doubt it has something to do with his supply chain or he is sick of dealing with us
or something but anyway we will let him just fitout the electrical how it was quoted in the specs and we will make our own changes later. But it is an odd way to conduct a business......EG stupidly inflate a price so you dont have to do something!! Not that he would care too much about his reputation he is one of the busiest builders in the state and has been for 20 years.
Not too much will get wasted. Ill use any gpo I remove from the house in the shed somewhere and if I put dimmers on a few of the lights Ill use the old switches in the shed as I am putting in a toilet, store room and have future plans for some other man cave ideas so theyll get used.
