Where can shop with an iTunes gift card?

Hello

I recently got given a £50 iTunes gift card.

Just checking... will it work in iBooks and both App stores?...And if so... can I pay for in app subscriptions and purchases with it?

Where will it not work?

Also, I activated it on my Mac but want to spend some of it on my iPad.. please let me know if there is something I need to do to use it there.

Many thanks in advance
