New Orchid! First Time Ever! Please Help!

[ScarletLycrois]

: I purchased a orchid from the store yesterday at a bargain price, but I don't know how to care for it. The flowers have fallen off (Which is probably why it was discounted) but I'm pretty sure it'll bud again?

How do I make sure the plant still flowers? It's nearing winter now too so do I have to make sure the plant doesn't get cold? (Sounds silly but do plants even get cold?)

It's a twin stem orchid that had (white flowers I think?) I know it's had flowers they just dropped off naturally in the store. How long till they grow back again?
Oh also, it's pretty tall, at least 30cm!

Please help me & tell me how to make sure the orchid doesn't die and flower again!
