Just like the iPhone 5, inventory of the iPad mini is finally starting to improve. Since its launch, production of the $329 iPad mini has struggled to keep up with high demand. Customers looking to buy the smaller tablet faced low in-store inventory and online shipping delays of two weeks. This situation is gradually improving as ship times in Apple’s US online store recently dropped from two weeks to one week. Customers who want a mini for their loved one this Christmas now have until December 12 to place their order.
