I ordered a Dawes Bullseye fat tire from bikesdirect after searching for a budget fat bike. Despite being such a large item, it showed up as promptly as it could. I'll say it was TOTALLY worth the wait! I've had a blast with the bike so far, especially when I remember how little I paid for it.
If you want to avoid the hassle of salesfolks trying to upsell you (I know I can't stand it.) and impairing prices, definitely consider giving bikesdirect a try.
