What do you think about an app for discount Easter eggs?

[CorgApps]

Hey Guys! I have an app idea I would like to share with you. Any feedback is welcome!

Easter Eggs -

The basic idea is to spawn little icons through out the site (At random times or set times predetermined by the merchant) the customers can then click the little icons/Easter eggs

once they do a popup appears with a discount code. (percentage set by the shop owner)

Would you use that? How much would you pay for it?

Any help is greatly apricated!
