If rain curtails your shopping activities, duck inside downtown Vancouver's main mall. You'll find all the usual chain and department store suspects, plus highlights like H&M, Purdy's Chocolates and Harry Rosen. You can also check your email for free at the Apple Store. There's a large food court if you need a pit stop from all that retail therapy.
Check the mall's website for an up-to-the-minute listing of sales and deals at the stores and eateries here.
