You generally have two options
1. go for the "free" gift which will cost you more
2. just renew without the gift for less money
Works out that you are probably getting the gift for less than retail but still paying for some of it.
EDIT looks like the current "gift" is a discount on a digital sub when you buy print + digital. Though it does not look as much of a discount as the advert would make you think!
