I'm about to order a 27" Core i5 iMac and would like to get the wired keyboard with numeric pad instead of the wireless one. Would this simple change be considered built to order to Apple? Is there still a policy about not being to return BTO products for a full refund? I'm in Canada, in case the return and refund policy differ from the US. Googling for the obvious "Apple BTO return" does give me results that Apple simply does not accept returns or refunds for BTO products but looking at their current return and refund policy on their website says nothing about BTO. I do remember seeing such a policy back in 2006 when I ordered my MacBook, which happened to be BTO. I'd just like to have some peace of mind knowing I could simply get a full refund in case I'm not satisfied with my purchase for any reason whatsoever.
