Learn how to crochet at Wholesaleyarnstore.com

I m new and trying to learn how to crochet and I found this website http://www.wholesaleyarnstore.com/ lately and they have different lessons step by step to learn how to crochet, anyone can advise me where to start.
I m not sure if I can share this here but they have hundreds of different yarns and I have a discount coupon "YARN123" that everyone can use.
