Hi everybody,
I registered especially just to say this so be grateful.
I have applied the three codes on the nokia shop and pre ordered my N900, with the price of £306.45. I didn't use topcashback as I am too lazy.
I then emailed Nokia customer care regarding the codes and their validity. I recieved the following response.

Thank you for contacting Nokia Care. We appreciate you choosing Nokia as your preferred device.

I hope everything is well. With regards to your email about the discount code and the expiration of this. We have checked this and rest assured that even though the Nokia N900 will be shipped after the said expiration date, the discount will still apply. Rest assured that you will only pay £ 306.45 when we ship the phone. Thank you.

Please don't hesitate to contact us again if you have any further questions.


I will leave off the name of the guy who gave this response just in case he gets shot for this.
