When you order something online from a place that has many retail stores does the order get fulfilled from anywhere?

Yesterday we ordered something for our house. The local stores of the retailer (three within 50 km) don't have stock so only way was to get it online (with no indication of where the stock is located) and shipped. Just seen a tracking notification indicating the order has been fulfilled by a store about 300 km away! Eek.

We don't do much online shopping so curious if this is a normal way that an online order gets managed?
