Voucher Codes!

Afternoon all, So I have been looking at getting an alienware M17x R4 for a little while now. I have seen that dell constantly have 10% off voucher codes that apply to their alienware products as well as other laptops. I missed the voucher that ended yesterday as I was only ale to get to the bank this morning. Is there a new 10% discount code that I can use? If not does anyone know when a new one will be released? Thank You
