As much as I love my, sorry my son's Thomas the tank engine train set he got for christmas, how many batteries do I have to buy for the blinkin thing.
We're just into week 3 of the new year and so far 5 changes of batteries!!!
I need to buy rechargable right?

Oh yes ... rechargeables are a must have.

When you have a spare minute, have a look at how many battery operated noise machines your son has, and then work out how many batteries are currently in use. Believe me, its scary! Then work out how much money you have spent on batteries so far and then tell me how many shares in energiser you are going to buy at the end of the month
