When do the bikes shops start reducing their prices of new bikes

to make way for their 2012 stock? I know I should know this, but don't

Also, do Decathlon generally start at about the same time?

Cycle Surgery have already started, have a look at their website. Their popular bikes are not discounted (unsurprisingly) but there's quite a lot available with money off.
