Hungry Dog Electric Money Box US $5.99 Delivered - 6 Colours/Varieties Available
Looks like a good price for these, they go for US $8.99 and upwards on AliExpress. Quite a few reviews & pictures here & here. It was fairly popular on Dealabs at a similar price.
Demo Video/Unboxing, go to 1:35 to see it in action. Requires 2 AA batteries.
Most suited for kids/shop counters/around the office etc. I would imagine.
Pay in USD = ~NZ $8.20 using today's VISA rates, or you can just pay in NZD on the site and it's NZ $8.34.
Remember to unstick shipping insurance at checkout.
