Coupon doen't work

[Bonniej]

Anybody have any suggestions on how to get a coupon to work in the MTU store. I got this email from Lynn Cox today. When I put the code in
it tells me coupon not valid.

To get your free upgrade, place and order for the Video Hoster upgrade for
$69.99. Enter check or money order as your form of payment, the in the box just
below that you will want to enter coupon code ####### This will make the
upgrade free for you. This is only good through the end of August, so please
upgrade for free while it's available.

Thanks Bonnie
