Converting Bonus Points to Gift Certificates

I've been thinking about converting my points to a gift certificate. Thought I might give it to my Mumsie. I don't know if she will use it though, so I though I would ask how much about 700 points would be worth before I did any converting. I saw the convert tab in the bonuses window but was afraid to click it in case that converted it and mumsie wanted not a gift certificate! So basically I'm just wondering how much around 700 points would be worth.

1 dollar for every 100 pts earned..in ur case 7 bucks

Well, that's better than nothing! Thanks for the reply!
