Dont bother sending slide film to Dwaynes in a Kodak mailer. As of 3/30/09, Kodak will no longer honor dated mailers no matter if the date is later this year. Plus, theres a report today from a fairly accurate source stating that not only the dated but now the undated mailers will not be honored. I'll check into this in the next day or so & post any updates. When I checked yesterday, the undated mailers were being accepted.
