Besides transitioning to online sales, there's a good chance OfficeDesigns hasn't changed all too much since I joined their mailing list way back in college while working at the University advertising department. More than 15 years after graduating I'm still receiving their catalogs for task chair, lighting, and office storage solutions (it's funny to see "UC Davis Advertising" printed on the mailing address).
I think I remember purchasing my first task chair through their mail order catalog while training to become a graphic designer; this was before the influx of high design, technical task chairs, but from that day on I understood a good task chair is as important as the computer your work on when it comes to day to day productivity.
One thing that remains the same are the competitive prices, with free FedEx delivery and no sales tax sales on Herman Miller, Steelcase, Humanscale, Knoll, Kartell, and BluDot brands.
OfficeDesigns.com guarantees the lowest prices on the Internet with a national price matching guarantee, so that means if you can find a better price either online or in-store, they'll match it. They also ship most of their products within 72 hours, making it a good option if you're setting up shop on a deadline. And if you happen to live near Chicago, you can visit their showroom in Northbrook Illinois where they offer floor samples at notable discounts (they're currently running a sample sale right now until Sunday, April 29th).
