I am waiting for a 15% off midnight sale to buy a nexus 4, their site seems to say it is in stock.
Never purchased from them before, how are they?
Even if they have a 15% coupon it's unlikely the Nexus 4 will be included in the list of eligible devices. It's happened often before. It's upto 15% off but generally they never apply it or apply the full 15% discount on premium in-demand products.
I would be super surprised if you did manage to get the coupon working for 15% off on the N4
