A little catch to it and I don't think I could be arsed doing it but here goes:
Buy any laptop along with a 3 year extended warranty and in three years exchange it for a brand new model to the same value absolutely free.
How to qualify: Buy any laptop with an appropriate 3 year warranty (listed below)
Then 30 days after you receive your laptop, complete and print out the online registration form here. Send the printed form together with a copy of your invoice to:
Laptops Direct Exchange Scheme, PO Box 661, Harrogate HG1 9HN.
You will receive a claim pack by post.
Return your laptop after 3 years and you will be sent a brand new laptop to the same value as the original purchase.
