Yes but you cannot put the flier in the mailbox. Stick it under the door or wedge between screen door and main door.
That should be fine. Avoid the mailbox, that s technically just for mail.Another option might be to find the best looking house, actually rake the leaves and leave a politely worded note and an envelope to retrieve tomorrow.Paradoxically, you ll probably earn more money if you provide the homeowner an options such as mitzvah and not demand payment.My kids ran two lemonade stands this summer. One was very specifically a free giveaway inspired by something we saw on tv. It was a complete failure, no one was willing to accept it without paying.
Yes it is okay. That is called good marketing.
yes.. best luck.
