Final answer:
Special conditions in a purchase agreement, such as warranties and service contracts, provide assurances that the seller will repair or replace the item within a certain period. They are particularly common with large purchases like cars, appliances, and houses. These conditions may vary by state due to specific laws.
Step-by-step explanation:
Special conditions included in a purchase agreement serve to provide additional protections and assurances for both the buyer and seller. For instance, sellers may offer a warranty, which guarantees the repair or replacement of the purchased good for a specific time frame. Furthermore, service contracts might also be available, where the buyer can pay an extra fee to ensure that the seller will repair any issues for a designated period post-purchase. Such contracts are frequently considered when large items such as cars, appliances, and houses are bought. It's essential to note that the effectiveness of these special conditions can vary by state, as some states have specific laws regarding the disallowance of disclaim warranties or the exclusion or limitation of liability.
