Saving comics to your Wantlist ensures you’ll be notified via email when that item is listed for sale. It’s also perfect for those comics you want, but aren’t ready to buy on the spot.
When you see an item you want on Comicogs, click ‘Add To My Wantlist’. 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!
