Spanish

Why hello there! I come with a question. I've recently started working at a music store in my local mall, and well, often we have Spanish speakers come in that barely know English. While Spanish is my major, I'm no where near fluent and while I do know the words for 'cd' and such, I haven't learned phrases yet that would be useful in retail.

So, I would like to know, what are the best ways to say things like, "Is there anything I can help you find today?", "Would you be interested in purchasing (insert item name here)?", and other similar questions.

Thanks guys!
