Your order was assembled for shipping on Saturday. This means it was put in a box with a UPS label on it. Then you know what happens? UPS need to come and pick it up, but guess what? They don't do Saturday or Sunday pickups. This means it will be Monday before it's shipped (or Monday evening as UPS tends to do pickups in the evening time) which means it will be Tuesday before UPS has it in it's system with an esitmated delivery date. This is a UPS issue not a GoPro issue.
If you had ordered from another retailer (such as Amazon), it would be the 31st before you could purchase the item with a 2 day delivery time (if you're a prime member). So you're still going to get the camera earlier than if you had ordered elsewhere online.
