I've been a fan of Famous Footwear for a long time, for a number of reasons:
1) They keep all of their inventory on the showroom floor, so you don't have to constantly hassle a clerk to fetch you another size or model.
2) They stock a variety of name brands that offer variable width sizes, including my favorite New Balance. Working for years on my feet has likely contributed to requiring a wide size and I am continually stymied by other traditional shoe stores not offering those options.
3) BOGO. Fairly regularly, Famous Footwear will host their "Buy One Get One Half Off" Sale. This is when I make a beeline and pick up two pairs of shoes.
4) Frequent Flyer Miles. If you sign up for their membership, you will often get discount coupons and incentives in the mail. This keeps me coming back.
And to have a Famous Footwear within a reasonable proximity of me (Chandler) is another big factor in my shopping there. I have always found their staff to be friendly and helpful.
