How much does a Great Pyr cost?

I'm curious, could you please elaborate on the cost of owning a Great Pyrenees dog? Are there any initial expenses that I should be aware of, such as the purchase price of the puppy? And what about ongoing costs like food, VET bills, and grooming? I'm trying to budget for this potential addition to my family and would greatly appreciate your insights on the financial aspect of owning a Great Pyr.
