Thanks, Helen. However, in this case I have to disagree. 'In Stock' generally means that it's available for immediate shipping, not that my order will put me at the back of a queue for shipping once it's really available.
Stating, "Adorama is receiving the lens and fulfilling preorders," would be an accurate statement.
Agreed, sort-of........ with the exception of when the quantity of units in any single delivery enables us to fulfill all pre-orders/back-orders, AND we still have some over for orders placed more recently. However, as we won't usually know how many units are going to be allocated to us within a single delivery - or how regularly we are going to receive them - we would never want estimate the likelihood of an order placed today being fulfilled within the following day or two. Especially if you add to the mix cancellation by customers of back-orders!
