We're having a local community Easter Egg Hunt for 29 kids, so I did quite a bit of research on these. Working out at 10p each these come in cheapest I can find, including places like Poundland and Homebargains (8 for £1 and 144 for over £20 online). Available in store and online (free C&C over £10 or £3.50 delivery). They are large enough to comfortably hold a creme egg, and come in bold colours useful for kids to spot in the undergrowth (for those people of a certain age, I'm betting you said that last word in David Belamy's voice). Just waiting now for Tesco to start doing their offers on medium sized eggs.
