How long does it take Stila to ship products?

I really want this smudge crayon eyeliner/eyeshadow thing in navy blue. They sell them at ulta for $22 but on their site they are only $16 and I heard that navy blue eyeliner looks good on light blue eyes. ANYWAYS, I was wondering how long it will take stila to ship their product to my house because in exactly 1 week from today I will be going back to college. I'm worried that if I ship it to my college, it will arrive too early and maybe the mailroom won't store it or something bad will happen to it but if I ship it to my house I'm scared it won't get here before i go home. Any thoughts?

Also, do you think that the $16 is a waste of money? I have another color of that product and I love it but I just don't like to spend money.
