OPTIS Product Options, Variant

I am just implementing this app on a new collection on my jewellery website...with over 30 different gemstone options combined with different chain lengths and matt or polished finishes the permutations are vast. This app is a breeze to use and seems to work seemlessly. You can choose the products you want to add it to and give different options for different products. Extremely versatile. I do need an option for an add on price for a couple of the options so spoke to Emma at BSS help - apparently this option will be available shortly and still free. (Emma was super helpful). Loving it!
