I asked this on Friday, but I didn't get any response, so I'll try one more time (just in case). Does anyone have any experience with bundles/add-ons that verify/clean shipping addresses of customers? we have a big problem with inaccurate addresses, and we're getting charged a hefty fine to fix them by the carriers. Any help would be greatly appreciated. Even if you've heard of them, but don't use them. that might also be helpful too. Thanks in advance!
