You should have been trying to add it to your cart and then apply the discount code to find out.
Well, in wooCommerce page they still have a 30% discount (from a previous sale that still shows on their website still) for smart manager product which is confusing. So, maybe you should have tried to resist the urge of being a smart ass?
If you don’t have anything useful to say, Mr. Obvious, you may just try to ignore the thread. Try it, I know you can.
It would have been useful, if you never tried doing that.
Sorry for trying to help, it won’t happen again.
