Communicating the price on a single service, single price website

Having a pricing page or section that follows conventional pricing table design patterns seems to be a best practice for websites offering different services.

If a website offers only a single service for a single price, there is no need to compare different services and prices. The homepage could describe the service and show the price somewhere (e.g. price sticker).

Would such an approach have any drawbacks? In other words, would it be useful to have a separate, conventional pricing page/section even if the website offers only a single service at a single price?
