How to get money VERY quickly
To get money extremely quickly in Hay Day, first, go hunting through your newspaper, and other people's newspapers, for construction equipment and saws, dynamite, and other goods selling in buld (I.E. 5 for 400 or something). Buy them all. Then, turn around and sell them individually for between 180 and 220 coins apiece, and put an advertisement on the very last one you list, so that when people go to the store, they will see all of them.
