adding free product to basket

Hi there,
I am trying to add a 'free stickers' product to any orders over 'x' amount (or with any order) - is it possible to set that up, preferably s that the free stickers are added automatically to the basket once another product is added?
I have tried - but can't work out a way to make it work
Many thanks
S
(in the process of upgrading product - need to make more space for backup first!)

Hello,
Can you give me more information about what you exactly want to do through some screenshots of where and how do you exactly want your "free stickers" to be displayed ?
Thanks.
