I saw in a thread a few days ago dimensional weights are not supported. I'm wondering the best way to approach my situation. I am a new FoxyCart user, have browsed the forums, and apologize if I've missed this particular issue. I'm using WordPress with the Thesis, and have reviewed the wiki integration page for Wordpress.
We sell fiberglass hulls for model ships, as well as small, compact accessories for these ships. The ship hulls are light weight (7-8 pounds shipped), but long (most are 4-6 feet long). We have three sizes of boxes for shipping. The smallest size box will ship USPS parcel post fine, but the two bigger sizes hit their balloon/dimensional limits, and get charged at the 20 pound rate. The three boxes don't count as dimensional weight for UPS and Fed Ex ground, but they do count as dimensional weight for air freight (3 day air was $45, 4 day ground was $15, as an example). The accessories we sell are compact and can fit into flat-rate shipping containers, but if they're ordered with a hull, we'd put those items in the long box with the hull.
One idea I had to get around the dimensional weight issue is to see if I could use two different weights for a product, depending on shipping method and carrier. If someone wants the hull shipped by air, I'd code the weight as 20 pounds. If they wanted it shipped by ground, I'd code it at the actual weight (say 7 pounds). Is this possible? If not, I'll likely put a note saying that shipping by air is much more expensive, and the customer can contact us directly for a quote (I'm new, but am assuming there is some way to do custom shipping or invoicing charges). I'd also need to disable the USPS option for our two larger sizes of boxes.
Can I write a condition that says if a hull is ordered and items that would normally ship flat-rate are ordered, to not charge shipping for the small items, or to just charge a couple of dollars handling fee?
I'm thinking I'll need categories here, but am not sure best practices on those. I have only just started installing today. If some of these questions have been answered elsewhere and I just didn't understand that it was an answer, I apologize and ask that you throw the appropriate link my way. I'm looking forward to SuperShip being released!
