The answer is yes for US customers. However, I can't speak for how Apple conducts its pre-order business in the UK. Having said that.... IMO it would be a poor business decision not to accept credit for a pre-order.
Not only will they but they welcome it. You may take advantage of there 0% Financing as well. There is a minimum purchase amount but still. I Purchased my Iphone 5S and Ipad Air with the Barclaycard and just paid it off before the 0% came off. 0 Interest and i got what i wanted. I actually think that if people are considering the Next plan with AT&T they should instead look at using the Barclaycard for 0% and keep there monthly payments on AT&T low. my current plan is 130/Month with 2 phones a iphone and samsung note. that is for unlimited calling and 10gb data. financing through the Next plan would take me up another 100 per month for 20 months for 2 phones. I can do the same thing with the Barclaycard but it benefits my credit unlike the next plan. Plus then i own my phone.
