How does Bundle & Save work?

Every item marked Bundle & Save counts (single items under $550), and you can mix them: 2 items save 5%, 3 save 10%, 5 or more save 15%. The saving is taken off automatically in the cart — there is no code to enter.

Do I need to be in for the delivery?

Orders over $150 ship with signature on delivery, so a missing parcel can be claimed. Your tracking number is emailed the moment the label prints.

Who can buy this refrigerant?

Under section 608 of the Clean Air Act, regulated refrigerants are sold only to technicians with EPA Section 608 (or 609) certification. By ordering you confirm you hold it; we may ask to see it before the order ships, and refund in full rather than ship to an uncertified buyer.
