Half Life 2 Overpriced!

The Bronze package on STEAM is $49.95, and in sterling that's £28, but on Amazon.co.uk they are selling it for £26.99! So by ordering the DVD off amazon you save £1.01, than if you bought it over STEAM.

Now to my point.
STEAM is digital distribution, it cuts out a lot of the middle people that usually take a big cut of the money, like the retailer. So even if they sold the digitally distributed copy a lot cheaper, Valve would still make more profit with the STEAM copies than the retail copies. So I am annoyed because I was expecting to get HL2 cheaper over STEAM (I was expecting at least £5 saving,but it's more!!!).
