Pricing calculation problem with product base price

I love your plugin and it’s helped us a lot with our product. However there are a couple problems I’ve encountered.

I have a rental product which at it’s cheapest costs 2500 NOK. However it is possible to rent it for longer periods of time, so I have made a button selection field where the user can see the price of each rental period. However, to not have the cheapest option be 0 in the extra options form (making it look like the cheapest rental i 0, although the base price is 2500), I’ve had to set the base product price to 0, so the cheapest option in the button selection field could be 2500, or else it would confuse customers. I’ve had to hide the product price from the page so it doesnt show 0, since the price is determined from the duration they choose in the first button selection field.

The problem then becomes that the product can’t synt to Facebook or Instagram because the product has a price of 0, but its actually “from” 2500 NOK.

There should be a way to make the product base price cost 2500, and for the price of the duration to display “From 2500”. Or to set the product price to 2500 without it being added to the calculation of the total.

Another way to solve it could be to allow to add a “+” symbol to the price, because then I could set the product base price to 2500, and the cheapest duration to +0, and then the others to +1500, +2500, and +3500.

Please check the website and you will understand the problem easier. Could you please make a fix for this?
