Snow Brite,
I did click on that section and I got a message that I had already taken advantage of that offer that month. I was told by My Points that the offer is good once per calendar month, not every 30 days. I had ordered in January, and this happened in February. I am sure that I will eventually get the points, but they are making me wait 20 business days before they will give me the credit (with my confirmation email sent to them of course).
This month going to wait until mid-month and hope that this doesn't happen again. What a pain!
