What is the best way to sell Apple products? - See details?

I recently won/purchased quite a few Apple products - x2 iPad Air (both white), x2 iPhone 5s (both black), x1 iMac 21.5".

As well as these I have also won a set of Beats headphones, a Kindle HDX Fire 7" and an iPad keyboard case.

They are all brand new, unopened. I would like to sell them for the RRP price (the price you would buy in store for them). I can lower the price by maybe £50, but I would like to get as much as possible for them.

Where and how do you think I could get the best price for them?

Ebay or as an Amazon 3rd party "New" seller
