Due to Advanced Primate's business model some brands and sales are only on the site for a limited time. In those cases we won't always restock something that we've sold in the past.If there is a particular product that you're interested in that's currently sold out, we recommend signing up our newsletter located at the bottom of any page on our site. We send out restock notifications for popular items that were previously sold out as part of our service to our newsletter subscribers.Once you've done that, rest assured that you will be notified if and when that item is back in stock!
