These words signify expenses that are beyond the normal range of personal or household budget, and typically relate to luxurious items, specialized services, and high-end products. Unlike budget prices, these antonyms indicate that the cost is not their primary concern, and the quality, exclusivity, and uniqueness of the items matter more.
