You can't do that. Apple and suppliers like them tell you when you're allowed to sell their stuff on sale, you don't get to set prices yourself. And bundling is also a giant no-no unless you have permission (which Apple would not give).
Absolute garbage. Apple do not price fix. That would be blatantly illegal. Suppliers can set an RRP but there is no obligation on any of our retailers to price accordingly.With Apple products the retail margin is very, very slim; which has the effect of retailers mostly selling at the RRP. 10% off Apple would be a small loss for the retailer.
Apple absolutely allows and even encourages promotion of its products, including bundle deals. They are preferred to discounting of the RRP in fact. You are correct in that Apple requires retailers to submit marketing plans to them prior to go-live, but this is around approving how the product is presented, not the price or promotion.
