From time to time, there will be a discrepancy in our Inventory Management system as we not only support online sales but in-store sales as well.
The odds are, around the same time you placed your order online, there was a sale made in-store that took the last of the stock off the shelves. It takes up to 15-minutes for sales to reconcile across in-store and online.
We have weekly orders and deliveries from our suppliers, so rest assured, if we're out of stock today, we'll be replenished within a couple of days, at which point, your order will be picked, packed and sent out to you!
