I'm getting screwed again by online shops

How long would you expect mail to get from North Carolina to California, if I sent it off last Thursday morning??? I'm just curious, cause I think maybe I'm getting screwed seeing how i sent them a lot of money and they claim it hasn't gotten there yet. Really, does it take a whole damn week for mail to get cross-country??? If not, I want someone from CA to go in there and woop their azzes and get my money back!!!

I'm getting tired of waiting forever for my parts to get to me :( If they don't get it by tommorrow, someone's gonna get HURT!!!!!
