There are some little freebies which you can order from the Chapman's kids club online - everything from keychains to t-shirts!
When you or your kid joins the club, you can play games and undertake activities online, in which you collect reward points. The T&Cs state that you can earn a maximum of 600 points per day.
In the prizes section, you'll see the things you can claim when redeeming your points. As I write this, the magnets and pens are out of stock, but there are free keychains, bookmarks, notepads, and highlighters available (and more).
I'm not entirely sure I agree with this freebie though. It really is marketing aimed at getting the Chapman's brand into the heads of innocent young kiddies. But a freebie is a freebie… so you'll have to think about your own ethics before you let your kids login and play!
