what sould I do?

I'm not sure whether or not this is the right place to put this but I'll take a chance lol. Any way I've got $250 Australian $ and I want to spend it on horses but there are so many things my horses need like a training bit for mouthing ,a breastplate, and some other stuff what do you think I should do?.
And possibly a saddle for one of my mares, any good things I should so get?
For my horses.help I don't want to spend it on crap.

You will need a lot more than that for a decent saddle, so I would scratch the idea of a saddle. Make a list of the most important you need and work on your way down.
