@jschlich - We determined that we do not have the ability to limit shipping options during checkout without spending a huge number of dev hours, so the only real option is to turn off prepaid shipping for your Trellis account (all of your listings). You then have the option of not charging shipping or collecting shipping via the reimbursement system. Here are the next steps as I see them:
This will eat up a half day of dev capacity so please let us know whether or not this is correct/you’d like us to proceed. Thanks, John
