Essential Free Shipping Bar

Stop giving away Free Shipping! Instead, start using the 'Free Shipping bar' progress bar which boosts your sales. Because when customers see "You're only $20 away from Free Shipping!", they actually spend these extra $20 (or even more). To make more money, just give them a cart goal value (e.g., $50) and a sweet award when they reach this amount (free shipping, discount code, or anything else). That’s it, click 'Install' and for maximum results use integrated cart upselling & cross selling!
