It's well nigh impossible to track anything on Hermes' website because they don't keep it updated. Something I received days ago still say it's out for delivery. Something else I bought was still saying "Order Generated" and nothing else a week after I received it!
I wonder if it depends on the actual courier driver updating it? Our Hermes courier is great, very reliable and must do whatever he needs to do to update their website. If I check online before leaving the house for work and see that Hermes tracking shows out for delivery, if I then check again at lunchtime from work it usually shows delivered and sure enough its waiting for me when I get home. I know I'm safe ordering from QVC, Next, Wallis & Debenhams as they all get delivered by the same Hermes courier. My heart sinks if I order from other retailers and get a tracking notification and discover it's not Hermes, because I know there will likely be problems. DHL are the worst in my experience - item sat in the local depot they'd subcontracted to with no attempt at delivery for 10 days and no means of tracking, and though UPS are very efficient with their tracking, they only deliver on certain days in my area and their 'local' depot is a 140mile round trip so me collecting from them is not an option. Hermes gets my vote every time!
