Just for your information, I don't think promotion codes work for pre-order. If you hadn't notice, when you add the pre-order item to your cart, there is no promotion code slot.

Also, from my 5 years of shopping experience from newegg, all the promo codes they email you is universal, which means they're all the same on every email they send out. Therefore it's pretty much safe to share with us.

Anyway, I don't see how you're able to obtain a 10% coupon from newegg. The latest promotion email I got from them doesn't seem to have a 10% coupon for use on any item.

One final thing, go with Newegg because they have great customer service and depending on how far you're from their warehouses, you can actually receive the item the next day you order.
