Free shipping on all orders until 18th Aug. Not sure if the free shipping applies to orders placed online via Staples.co.uk but does apply to orders placed via their freephone order line (0800) 14 14 14.
Important (apologies, didn't realise this whilst submitting original post):- Order something from their flyer with codes beginning "3B" and the shipping is free of charge. An example is posted here:-http://hotukdeals.com/forums/showthread.php?t=21661
- Buy something like a box of 500 paperclips 3B-333 344 @ £1.79+VAT add free gift code 3B-Remote and the order total comes to only £2.10 including VAT with no delivery charges. - MacNewbieInTraining
