Under normal circumstances it's very difficult for us to combine orders. We process a high volume of shipments and combining an order must be done manually, is quite labor intensive and requires a lot of additional oversight to ensure an order is combined properly. For this reason we currently discourage combining orders, but we are always looking for ways to make that process easier for everyone involved.
Sometimes during an event like a live sale we may invite our customers to contact us if they'd like to have orders combined. On these occasions, you can submit a support ticket and let us know which orders you'd like to have combined. Please keep in mind your combined order won't ship until all items have been received at our facility and are ready to be packed for you.
