INHALCO review for Addly Bundles app & Upsell app

The pricing is unreasonable because it increases with our sales volume. For sales of $500-$1000, the cost is $24.99. For sales of $1000-$2500, the cost is $44.99, and it keeps going up from there. I’m not sure how the plugin calculates which orders it attributes to itself. After installing it, I didn’t notice a significant increase in overall site sales or conversion rates, and even after uninstalling it, I didn’t notice a significant drop in sales. But its pricing is on a sliding scale. I'm going to try a different plugin instead.
