Tulip questions

Tulip questions

Well I notice that everyone is talking about how unsually warm things have been this winter. I'm very glad of it actually. I'm down in zone 9 and several trees are already getting new green leaves. I was surprised to find Tulips and Hyacinths at some garden centers. I thought it was rather early, but I'm glad to see everything coming up. I have a feeling spring will come early and I'm probably gonna get a jump on my garden in another week since I just got my first seed order in. I just love tulips. They are bulbs aren't they? Do I have to buy them as bulbs or can I just buy the ones I saw already blooming at the store? That's what I'm contemplating doing. Also I read some of you saying that you have to bring the bulbs in when it's winter unless you're in a warmer area. Would it be ok to leave them out all year? Also why do they come in bulbs? Don't things like tulips make seeds? Yes this is all new to me. Please let me know.
