On all other products which are not on special, the attribute shows $2

but when i add the attribute to a product that is on special, it changes the value of the attribute to $1.80 even though i set it at $2...

why is this happening?

example,

http://toyopia.com/index.php?main_pa...9cc78869c86c92

it should show $2 when you select gift wrap

below the product is not on special and it shows the attribute correctly $2
