Saving an item to your Wantlist ensures you’ll be notified via email when that item is listed for sale. It’s also perfect for those items you want, but aren’t ready to purchase right at that moment.
When you see an item you want on Gearogs, click ‘Add To My Wantlist’ from the right-column on the item page. You can browse (and check items off) your Wantlist any time, find it in the drop-menu from your username in the top-right. Don’t forget to remove your Wantlisted items as you get them!
