We use it as a great opportunity to pass out gospel tracts. Imagine, people coming to your house to receive candy attached to a gospel tract. That tract can get into homes where I may not be able to get. That tract may be read and passed around to several people. That tract may be a blessing to believers coming by and may prompt a believer to awaken. We give tracts and leave it to God in prayer for the results.
