I have the standard USPS shipping module that was modified with the "Individual Product Shipping Methods" (http://addons.oscommerce.com/info/4674) contribution. The USPS module works fine, and I have been able to comment out the services I do not want to offer. The problem is that we have a document that we make available on the store that is a single sheet of paper that would mail in a no. 10 envelope and should be able to mail First Class Letter for $0.44, but for the life of me I cannot get that option to show up. I have searched the forums and have not found a solution.
I have checked handling fees, tare weight, product weight, and anything else I could think of that would effect this.
I am using version 2.2rc2 of osc. Any ideas.
