Yay!!! good result from Anaconda.
I took both tents back to Anaconda this afternoon. I went to the front desk and spoke to the shop assistant there.
I explained what issues I had with both tents and his response was
"We will refund $429.00 for the Jardine as that is the current price in the catalogue" - on special reduced from rrp $600
"We won't give you any refund for the Canning as we don't stock them anymore and it is over a year old"
So I wasn't too happy with this as we payed full price for the big tent (Jardine), the little tent (Canning) was only $70 so I was not really bothered about that.
So I patiently listened to him wielding his bit of power for a little while, saying he couldn't possibly refund me fully as there was no receipt and the tent is cheaper now etc
Then he said he wasn't authorised to make the decisions regarding refunds. So I asked to speak to someone who could.
The store manager came out and was really good. He looked up the average price that both tents had been sold for in the previous year (Jardine -$450 Canning -$100) and we agreed on $550.
Which was a good result for me, considering I had written them off before posting here.
The Coleman 12 CV Montana was on special for $749 with a free Coleman gas lamp (rrp $129) so I got one of them.
I know I could have got the coleman for $50-$60 cheaper elsewhere but I needed a new lamp anyway. So good result all round for me and Anaconda get to keep me as a happy customer.
Thanks for the advice you have saved me a lot of money
