You can find free pallets in various places. Local businesses like garden centers or warehouses often have pallets they're willing to give away. Construction sites and home improvement stores may also have extra pallets available. Online platforms such as Craigslist or Facebook Marketplace can be a good source. Additionally, check with retail stores or explore industrial areas where businesses discard pallets. Remember to ask for permission and prioritize safety when collecting pallets. Inspect them for damage or chemical treatments before use.
