I can't imagine who buys those plastic-wrapped baskets. Each of ours cost about $2, with half that going to Beatrix Potter chocolate bunnies from Dollar Tree. The rest are recycled eggs from other egg hunts and yard sale goodies.
To decrease the candy intake, I filled eggs with LEGO specialty pieces and mini-figs. The LEGOs were free with my Thriftsmart Reward money (spend $10, get a $10 credit). Let me just say, you cannot imagine the excitement we had.
