About This File
Adds an additional field in the Options section next to the price. The field = option price means that you can enter a price and, depending on the price of the product, the script will automatically write a + or - prefix and, accordingly, the price difference in the standard field.
Now you do not need to subtract each time in the options how much you need to add or subtract from the main price of the product.
Does not replace engine files, made with only one modifier!
Doesn't change the structure of option pricing, and doesn't add extra fields to the database!
Made for 3 versions of the engine. At the request, I will do for version 2 if necessary!
Those. support is present!
