Meaning of ETA: ETA is the abbreviation of "Estimated Time of Arrival".
"ETA to be confirmed" means the estimated time of arrival is waiting for the manufacturer's confirmation.
When an order was placed and containing low stock or back order item via our online order system, no matter the order is paid or not, our back end order system will list out those items and reminding our purchasing staff to advise the ETA, and our purchasing staff will follow up with the relative manufacturers to check the ETA, We will update the ETA information asap when get a confirmation from the manufacturer. Yet as you may easily understand, the ETA is mainly depending on the manufacturers, for some reason, it happen quite often that manufacturer can not provide an ETA in a timely manner, or sometime they even cannot provide an ETA, this is why sometime it takes quite long or even without an ETA information been updated.
