OPTIS Product Options, Variant

I had a hard time to find an app that has multiple variant options including file upload, and this app has it all! I also only found this out because I had an issue with another app which I was using the file upload for, and the BSS support chat Julie told me that it's all possible here. I also love the fact that chat is available when many apps don't offer that. She stayed with me the whole time of reinstalling to get what I needed! I recommend this app to everyone who is offering custom products for people!
