LayyeeBundles review for Globo Product Options, Variant

I used this app to help up sell my products. It was an easy process adding to my site....but when i launched my website with a discount code. The discount was not able to perform at all with the extra variants added to the cart. The support responded fast but the error wont be fixed for 2 Weeks which leaves me to figure out a plan b and have to sadly leave this app alone for small issue.
