That isn't the way it works by default, there is only one gift available per price point as he stated earlier. You could, however, have a couple of options for different price points. For example:
A customer spends $100, they are offered one free gift
A customer spends $200, they are offered a different free gift
You can't have a drop-down list of gifts to choose from if that is what you are looking for, at least not the way the code is written above. I'm sure Atul can write something like that though, for the right price
