VAPEVO review for Free Gift Box+Buy 1 Get 1+BOGO

Free but absolutely no support. Create me dozen of duplicated products when I have to update my offers. This app also added a new condition "ghost_product" to all my collections, so that all my products display in all my collections. That was catastrophyic ! Slow down my website with terrible SEO score, I sent them suggestions of the web speed test, they just ignore my message. I would prefer go for a paid app. At least there is a true support.
