Well, I guess then you have only two options:
1. If price and exchange rate of the product don't change, or at least not often, use an image editor and make the prices part of the image. (I dare guessing that's how the "shop now" button got there, too?)
2. If you require dynamics, such as prices coming from the HikaShop settings, you'll need to do more or less extensive code development, or hire and pay a developer to do it for you.
Obviously, for anything more on point #2 here above, you might (also) want and need to consult the Joomlavi guys.
