I agree the Acer cash back is a fraudulent scam as good as any that a Nigerian conman could cook up. I bought a Laptop in January 2010, registered it online the same day I bought it, got the caim number from Acer and sent all the relavent paperwork by express mail (guaranteed next day delivery) in 5 days so they would have it in plenty of time, thinking naively that this being a big, well known company and having sold their products from my own computer sales and consultancy business in the past that this would be a straight forward process (yeah right!). Now with the time limit almost up I enquired where are the $$ and was told I have to re-submit the claim number and information that they already have.
I also will never buy another Acer product and every person I ever talk to regarding computers will here of their shonky practices
