Free: Contests & Raffles.
Three hours? The next day? I can't see where waiting until the next day can help anything, except to ruin and waste your game. Waiting this long may also let sign get rained out. If an animal is going to bed down, it may do it right away, it may not, I can see how chasing it immediately could be a problem. Waiting an hour to let it fade I can understand. Three hours, come on. I also believe that you are responsible for a quick kill, and if you routinely are sticking animals and then walking away, to go back the next day, ...not really a nice way to end the animals life.
I disagree with all of the TV shows and so forth about leaving overnight. Even in cold weather, I think an animal will spoil or taste worse.
