My shop www.msno.no have alot of products with product variants. Rectify realy deliveres just what i was looking for. The instalation is easy and support was fast to reply when i asked for a couple of adjustments in the look of the «change» button.
Before i installed the Rectify app, my custommer had to delete product from cart when they wanted a different variant, now they can do it right in the cart.
I really love apps that make the world less complicated for our custommers, and the Rectify app is doing just that.
