Shipping processing times will vary seller by seller. You can find information about a seller's general processing timeline in their FAQs under "Payment & Shipping," or in the auction details under "Shipping."
If a seller doesn't have a specifically stated timeline, a good rule of thumb is five to seven business days.
Keep in mind that most facilities are closed on the weekends, so Saturday and Sunday shouldn't be included when you're counting up the days.
For most sites using binding shipping, you will be able to track your order by logging into your account, selecting "orders" from the account menu in the top right hand corner, clicking the order, and then clicking the hyperlinked order number in the right hand corner of the order details table.
If your shipment is outside the time frame, you are welcome to contact B-Stock to let us know.
