I've been a fan of The Paper Source for 10 years. I used to work down the street from the one in Beverly Hills and would spend my lunch breaks browsing the greeting cards and trendy gifts. The Phoenix store is as good as any location I've been to in California, despite being a tad smaller. The staff is extremely attentive and customer service is clearly a focus here. The staff also knows the wares well, which I appreciate it.
The big secret that most people don't know about The Paper Source: despite being a great place to get unique cards (and paper of course) is that they have unusual, delightful and sometimes delightfully bizarre tchotcky-type gifts that are usually PERFECT to accompany a card when all you want to do is make a small gesture, but not really buy a *real* gift for someone. Example: spherical ice cube freezing tray, whiskey stones, wine glass markers, convertible pens and little humorous gag gifts that you might've seen at Spencer gifts in the 1970's. When you just want to get your friend or co-worker a little "something" but it needs to be unique and you don't want to spend more than $10, this is THE place to shop for a card and a little something cool to accompany it.
