found the same bookstore on a trip to Chilliwack.. the shop is huge, really nice to browse, and i found a couple of books that i'd been searching for for a long time. they have a couple of chairs up front, and i settled into one and browsed some books... it was super relaxing. i found a great hiking guide for the area too.
The malls are only for main stream type stuff. If you happen to be closer to the down town area, Wellingdon ave. has some very nice shops, including a very large used book store with great prices, and a few nice clothing and jewlery stores.
Not very large but a alternative for a quick stop. Bellamey's (good fish and chips) and Decades (good coffe) are nearby aswell.
Note of interest, this street is where parts of the purse theft scene in white chicks was filmed, aswell as the site of a VW ad(winter ad, they used fake snow)
There are two malls in Chilliwack: Chilliwack Mall and Cottonwood Corner. If you walk into Chilliwack Mall, you'll feel suicidal, so don't go there.. Instead, go to Cottonwood.
What to buy: There's a Zellers and a Sears here, along with tons of other little shops
