If you use multiple pricing tables next to each other, they might not align, because some products might have more or less features than the others. Not sure if there is a better solution, but the following small script will fix this.
// align all pricing tables on a page to have the same height
// Could be further improved by aligning only those next to each other
var maxHeightPricing = -1;
if ($(this).height() > maxHeightPricing)
maxHeightPricing = $(this).height();
