Your best bet is to confirm with the flea market / swap meet the location, hours, etc. We have tried to preset as much contact information as we could find. Web pages, email, phone numbers, physical address area all presented as available. However things do change. In that case it would be a kindness if you or the owner could contact us so we can update our database.
Please do keep in mind we run this site as a hobby. We both have jobs, family obligations, errands to do, etc. We will do our level best to correct any errors that are pointed out but we can't always be johnny on the spot.
