Welcome! Like Bowslinger said, you can find a samick sage on 3 rivers for a cheap price, they even have a kit to help you start out for around $200.
It doesn't come with arrows, but even with the cost of arrows you are probably looking at about $300. Not sure how much the discount will help you, but that is about a 70 dollar savings. You will be able to choose from a whole slew of draw weights as well, so you don't over bow yourself at first.
The samick sage is a heck of a bow for the price, just the bow to get started with imo. You can do a search for reviews on em, I haven't seen a bad one yet.
