Some products have variations of the listed product on a product page.

 When you see a product variation on a product page listed with a [-$1.50] it means that variation will be $1.50 less than the product listed on the page.

A plus sign ahead of the $ means the product variation will be that much more than the product listed on the page.

An * ahead of the $ means that product variation is the per-centage shown after the $ of the product listed on the page.

An example of this is when the listed product is $50 and the variation listed shows [*$0.50] it means the variation will be 50% of the price shown for the listed product on that page, or $25 for this example.

Another example: if the variation listed shows [*$1.50] it means the variation is 150% of the price shown for the listed product on that page, or in the example of the $50 listed product, that would mean that variation would be $75.
