Each part on JasensCustoms.com lists where it will ship from and when it will ship. You can see this in the product preview before clicking it, or in the product page just below the price. Some items ship from SoCal, typically the stuff normally purchased for building a Panzer Fight Stick and the Panzer Fight Stick. The other items, more geared towards commercial fight stick upgrades ship from Florida. We do this to ensure the optimum shipping times based on the part time shipping nature of each location (the sales volume isn't quite high enough to support full time employees yet).
To facilitate orders that have parts from both the SoCal warehouse and the Florida warehouse we manually split them in our shipping software so each location can pack and ship the items they are responsible for, meaning you will get an order shipped notice from the main site's shopping cart when either partial order ships. This manual order split doesn't affect the main site's system so your entire order gets marked SHIPPED even if the second parcel hasn't shipped yet. When either partial order ships though, you will get a separate email from the shipping setup with a tracking number for that order and you will get one for EACH partial order shipped. See what it looks like here:
One thing you can do to save some money on shipping, if you want things from both warehouses, make two separate orders. It may make sense to ship a Panzer via FedEx Ground because of the size/weight but not so much for a couple of Pro Cables too. By placing two separate orders, you can choose the best shipping for each parcel coming from each warehouse.
