Another approach is to only PRE Auth on the site, which is a common practice and then POST auth at shipment. You can Post auth for a higher amount than the Pre Auth, once you determine shipping. If you want you can always send an invoice in between, but at least you have the CC so you know they are serious. Authorize.net and most gateways let you do that. On a side note there are a bunch of websites (like freightquote.com) that have API's for calculating freight based on weight and destination for truck shipments so the customer can know the freight before checking out.
