In all Fanatical Build Your Own bundles, adds "Add to bundle" button to the carousel - like in game bundles. It is handy to have arrows, to browse products, and button to add to cart close by. Also marks a tile of the product, currently shown in the carousel. In bundles with tiers, adds tier info to the carousel. All bundles: move carousel on top and use mouse wheel horizontal scroll to switch next/prev product.
