Why are the shops full of Easter eggs already?

Is it just me that finds this annoying?  So much hype!  So much marketing! So much 'stuff'!  The shelves are already crammed full of eggs in every shape and form possible. 

What truly annoys me is that the supermarkets put sweets at eye-level at the check-out counters... and one of them is my favourite.  Cadbury Caramello eggs.  Don't they know how hard it is to stick to a diet?
