Sometimes things go wrong. A present is lost in the mail, we find out we sent a present to the wrong person, or it turns out that the present is broken.
It is not too late to sort this problem out, however. And That's Christmas, together with sister site, That's Books can help you do this.
If you visit http://thatsbooks.blogspot.com/ and use the online That's Books dedicated online Amazon shop search box you can buy emailable Amazon gift certificates there in any amount you want!
Sorted! As we say.
And do have a good Christmas!
