Yes, automatically. Items ordered together ship together in one parcel from our Woodlawn, Virginia warehouse, and the free-shipping threshold applies to the order total rather than to individual items. Ordering separately means separate parcels and separate shipping.
Every order is picked and packed by us at 5055 Carrollton Pike, Suite C, Woodlawn, Virginia, and goes out by USPS. We do not dropship, so nothing you order is forwarded to a third party to fulfill.
Because there is only one place your items come from, combining them is the default rather than something we have to arrange.
Free shipping applies over $149 on the order total. Three items at $50 each qualify together and none of them would separately.
If you are close to the threshold, adding a small item usually costs less than paying the flat rate. See the free-shipping threshold.
If you placed two orders minutes apart and neither has shipped, contact us and ask. We can often combine them, though it is not guaranteed once picking has started.
