Free shipping is $100, and each product's price exceeds $100 automatic showed "Free Shipping". I put this in product.tpl:
<?php if ($price > 100) { ?><h4>Free Shipping</h4><?php } ?>
Is perfect, all working good, but a problem is when product price is up to $999... No showed message "Free shipping"
1.000, 1.001 ... Decimal no working good

I running opencart v1.5.5.1
Ideas?
