Depends on the route. The only time I flew EasyJet, I was going Amsterdam to London, and they are your only LCC choice, with maybe 2 flights a day, so they charge whatever they darn well want knowing you'll pay it. More popular routes, be prepared to fly super early/late if you want to save a few bucks. But no, they really don't have sales like RyanAir or SkyEurope or most other LCC.
