We are testing the free version of Woo Price Calculator, and are interested in purchasing the Pro.
We want to add an option to add a “free sample” in the cart (for some products). So the user can request a free sample of a product, without needing to specify any options or price.
We have found a couple of ways to add this function (independent of WPC), but they both conflict with WPC. WPC complains about the product fields not being filled in properly when we click to add the free sample to the cart.
Can you please give us an opinion on how this function can be possible, and work nicely with WPC?
