Easter Eggs are often a very expensive way to buy mediocre chocolate, but one way to join in the fun without breaking the bank is to wait until next Tuesday to buy. Some stores were already advertising Easter chocolates at 20% off on Saturday - desperate to sell their stock before Sunday. If the pattern of previous year's persists, come Tuesday the stores will be full of Easter Eggs at 50% off.
Of course the traditional method of having cheap Easter eggs is to use food dye and non-toxic paints to colour and decorate hard-boiled hen eggs. This is actually a fun family activity, and a healthy alternative to overdosing on chocolate.
