The letter + number in the title is for my inventory system. This tells me what bin and tab your item(s) are in, not the quantity that you are receiving.

eBay Standard Envelope only provides tracking updates when it passes through sorting machines. USPS workers have no way of scanning the barcode. When it marks it as "out for delivery/delivered" it means it has arrived at your local sorting center, not your home address. Depending on your postal route, it could take several days for it to arrive at its final destination. Delivery time can take upwards of 2 full weeks to arrive.
