Smart Product Filter & Search

(0 star) They say that you will pay for "Tiered pricing by catalog size: 500 → 500k products by Professional $39 plan, but it is not true. I do more have more than 40k products in my store, and they wanted me to pay them $350/month. This is crazy. And here on shopify store app, you can see that they have 4 differents plans including free plan, after installeted it you will not see these plan. The app is not even working as I want it work.
