By checking this box you understand that if you order aluminum(including kits) your entire order will be sent UPS GROUND ORM-D. If you order magnesium by itself or with other items besides aluminum it will be sent USPS ORM-D. Sulfur will ship regular UPS. ORM-D items can't be sent to Hawaii/Alaska. All aluminum and magnesium orders will be canceled from Hawaii/Alaska. ORM-D will extend the shipping time for those items.
