OPTIS Product Options, Variant

If you sell items that have customization options (like giving the option to select a specific type of accessory with a product and even making that a mandatory selection) this is the way to do it! There is a free option as well as a couple tiers of pay options depending on how much customization you want or need. I've been trying to do this with Shopify's Variants since I created the site but could never get it the way I wanted without doubling my inventory numbers just to allow the options. I saw this, added the app and created several options in a few minutes with no issues and it does EXACTLY what I need. Well worth the look!
