OPTIS Product Options, Variant

I have installed this app after using other for years. This is simply the best just beacause is simple to manage, create options, apply them to the products, and what is key for us it does not create temporary products that do not affect the product stock quantities. This app impact in the stock quantities so much one task I can forget.
Then the support is amazing, Cassie reply withing minutes if in working times. And the tech team also do a great job.
And all these features for free! It is a gift to every store owner with customizable products.
Thank you very much to BSS Team!
