The price on the vouchers through the other thread is $16.35 (tax incl.) plus shipping. The site was supposed to be for members of specific groups that have enrolled in the program.
Mousesavers (thank you Mary!) has negotiated a price through a branch of the same company that is available to the general public. It is $16.77 (tax incl.). Most of the same shipping options apply to both. I really think it would be more appropriate to order from this site and will not longer give out the private code for the other site. Here is the Mousesavers link:
Since I can be reasonably assured that the link that is being shared is to a site that is not for the general public, I think that it is better that this thread is just shut down to curtail the sharing of the link and code.
Sorry guys.
