Changing the Available tag

Hi there – love your plugin!

I was wondered if it’s possible to change the word ‘Available’ in the product listing to something else, not sure it makes much sense in the context I’m using it in so would like to be able to edit to read ‘Shop Now’ or something?

I’ve had a look at the php and css files and can’t see a way – everything I’ve tried has broken it so I thought I’d ask the experts!

Cheers
Sam
