Don't read too much into the 4 working day delivery. The glass that I
ordered was for an outside patio table with a center hole for an
umbrella. It might very well be a stock item. I didn't ask and at the
time I didn't care. The local shop has a supplier that "would delivery
custom ordered tempered glass" . I am guessing that my order was
filled with a stocked item.
