As title really, not sure how long this will last but on the dell outlet at the moment you can get £100 off all Inspiron models, including the Mini.
There are loads available, and the price will vary depending on what you select.
I'm very temptred by an Inspiron Mini 9 for £135, and a Inspiron 545 with Q8200, 4GB RAM, 640gb HDD and a tv tuner for £340.
These prices are Delivered!!
You need to select "BUY NOW & SAVE! VOUCH OFFER [price -£100.00] -SPECIAL OFFER-" from the software and peripherals section.
Hope this helps someone.
