If I buy my new iMac from the Apple Store(online or retail) I will have to pay sales tax. But if I buy from Amazon, I will not have to pay sales tax. So, why should I buy from Apple? Even if I use my student discount, it's still cheaper to buy from Amazon b/c of the added tax. Are BTOs and refurbs the only reasons? Am I missing something? Is there a way for me to NOT pay tax at the Apple Store? BTW, I live in Alabama not CA. Thanks. Also, does anyone know why Apple charges tax when most other online retailers do not?
