Ooooh, oooh, another fan of bead porn! I just got my new Fire Mountain Gems catalogue in the mail yesterday! Bliss! I call it my beadie bible.
I also love my IKEA catalogues. I haven’t seen a Sears catalogue in years and years, but I remember as a child, and even well into adulthood, I couldn’t wait to get my hands on the Wishbook each year.
I like looking through the O’Reilly book catalogue. Not so much for the tech stuff as to look at all the pretty animals. 
Daniel Smith - art supply yumminess. Also, yes, Williams Sonoma and Levenger.
Parts Express. Audio & electronics parts and products.
Yep, I’ve ordered jeans, shirts, and even a swimsuit from them (online). I like their stuff, they have good customer service, and their return policy rocks. 
Amen. Jeff Foxworthy said something like “Pictures of gorgeous models in skimpy lingerie mailed to my home free of charge? God bless America!!”
