I bought something from Noel Leeming online the other day and it's just gone on sale. I know I can buy it again and I have 14 days to do a no quibbles return but if I call them up and ask them to refund the difference in price will they? Cheers!
*Edit: I emailed them with all the details and they promptly refunded me the difference in price.
You can always try?
I had the same thing with PB tech last year, bought something then less than a week later it was onsale so i email them & went instore, then was refunded the difference.
