How much change should I get for a garage sale to ensure a seamless transaction process? As I prepare for this event, what denominations of currency will be most beneficial for both myself and the potential buyers? Should I focus on having a larger supply of coins, like quarters and dimes, which often play a crucial role in small transactions? Furthermore, is it necessary to have a substantial amount of larger bills, such as fives and tens, to facilitate purchases of higher-priced items? What strategies should I employ to estimate the total amount of change required based on anticipated sales volume? Would a careful analysis of my past sales or consultation with seasoned garage sale veterans provide valuable insight into the optimal amount of change to have on hand? Ultimately, how can I strike the right balance to avoid running out of money for change while also ensuring that overload doesn’t become an issue?
