Merchants must accept returns of products that do not work for their intended purpose. Purchases of both new and used products include implied warranties that guarantee that the product works, according to FindLaw.
The implied warranty covers the basic functionality of a product, such as a snow shovel picking up snow without breaking, all specifications on the product packaging, such as a statement that the shovel can lift up to 60 pounds of snow, and all promises made by the salesperson regarding the product, such as a claim that it would also work for gravel, explains FindLaw. The implied warranty is governed by state law. Some states allow products to be labeled for sale "as is" to exclude the implied warranty.
