My sister always requests the Christmas scents for Christmas, so I know this one!
Last year, they had a buy 3, get 3 free. I also had a $10 off coupon when you spend $30, so I ended up spending about $25 for 6 bottles of lotion. Which made not only her Christmas gift, but her birthday gift later in the year.
Now, keep in mind, that was last year, so I can't guarantee they're doing it this year, but I'm personally waiting a while to see if it crops up. Every little bit helps
