If you go to hmv.co.uk and click on "Coming soon" (near the top of the page - next to "New releases" in the centre) you will get a list of forthcoming releases on various formats. If you click on "Music Albums" (on the left of the page - near the top left of the page) you will get a list of forthcoming albums. Scroll down until you find the releases for November 11th 2002 and you will find "New Order - Box Set: Title To Be Confirmed". The price given for the box set is £16.99. If you think you're seeing things click on "Box Set: Title To Be Confirmed" and you will get a brief page about the box set which restates that the price is £16.99.
In recent months a few retailers have mistakenly advertised products at incredibly low prices on their websites, lots of customers have ordered them at those prices and the retailers have then found themselves in a very tricky position. I don't know if the retailers in question had to sell the goods that customers had ordered at the advertised prices or managed to get out of it. If you are planning on buying the box set regardless of the contents or price and think you could argue your corner in any dispute you may want to consider ordering the box set from HMV making sure that you get printouts at every stage of the transaction in order to prove that it was offered for sale at £16.99 and you ordered it at that price. I don't know if anyone at HMV.co.uk works weekends but it was advertised at £16.99 in the early hours (UK time) of Saturday 19th October 2002. If there is a rush of orders for the box set or requests for the webpage in question someone may spot the error and change the price advertised on the website.
I'm not an expert on consumer law and I've never bought anything over the Internet so I don't know if anyone will be able to get the box set for £16.99. If anyone does know how these things work you may be able to tell us whether or not HMV will have to honour any orders placed at the advertised price. I'm just telling you about this because I thought you may be interested and I'm not sure anyone else has noticed this potential bargain.
