Very poor service! Placed an order for a printer online which had a 20% discount code. Had confirmation email and all was well. After 1 week without delivery I checked the staples account to find out that the order had been cancelled, upon contacting staples I was told that the order was cancelled due to the use of an invalid discount code, when I asked how could it be invalid if it went through the checkout process and even accepted payment I was told that there was no further information available other than it was invalid. When asked why I did not receive any communication informing me that it was cancelled they couldn't answer this either. I have also been told that I will have to wait 14days to receive refund to my card for £169.99. Disgusting customer service and will not ever use this retailer again.
