When do Evans et al start their sales?

maybe there is always a clearance bit at cycle shops like James / Evans etc but I just wonder when the sale season actually starts

reason I ask is that in May this year Evans seemed to have a huge range of clearance kit like helmets & jackets but now its mostly odd sizes / products - I will be wanting to get a new jacket, shorts and helmet over the next few months, happy to hold out for a bargain as good kit seems pricey these days
