All, Need an opinion on this idea. Currently American Express membership redemption has a sale going on. it's 30% off current point values to apple products. Would this work if I buy 2 ipad mini now with my points taking advantage of the sale and hold on to it and once the new ipad mini comes out, I will go and exchange the old ones with the new ones? Would Apple honor the exchange? I will be purchasing using Amex points thru Apple stores. Just getting ready for my sons' Xmas presents.
