Variant Product Costs not responding sometimes


Some of our products have variants that affect the price. When viewing the product pages, sometimes these variant prices are responsive, and sometimes not!

Novella Outdoors - Decorative Umbrella Bases

The sails always show the default variant price, whereas the umbrella bases price changes depending on your design selection.
