I always used super saver delivery and the package came exectly the date they said.

Also their RMA replacements were sent using next day
When they ran out of stock they refund you the old price and you can choose a better product (I RMA-ed a SATA150 HDD and got a SATA300 back with extra 11 quids in credit note LOL)

But their packaging and handling is REALLY CRAP.

I have to RMA 3 times for my 2 HDDs (1 DoA, one died a while ago and 1 incorrect item). Their price was pretty good at that time

Just now the Maxtor HDD on offer was cheaper than SCAN's Today only a few days ago.
