We all know there are some new Ivy Bridge Macs coming in the near future, but is it best to jump on launch day or does holding off a few days get better prices? Dealnews did the research on the last three years of Mac prices and found customers could save hundreds of dollars by holding off just a few days. Waiting two days saves up to $45 on a MacBook Pro, one day saved $49 on an Air, and a week saved $94 on an iMac at various resellers besides Apple. Waiting a few months nets even more savings. Apple only cuts deals on Black Friday (and small discounts for students and companies).

Apple’s iOS devices do not lose value so quickly, so it makes much more sense to “line up” on Day One. Hit 9to5Toys to find all the latest Apple related deals.
