Let me guess - I had you at hello, right?
I discovered a store policy yesterday that I think you need to know about! At PayLess Shoes, if they don't have your size in stock, you can request a printout that shows locations nearby that have the shoe in your size. And, for the hassle of traveling to another store, you receive a $6 discount on those shoes (take the printout with you to the second store, that's your coupon). And, when the shoes in question are on sale for $6... well, that means FREE SHOES! For an eight minute drive (en route to where I happened to be headed anyway), I didn't even pay tax on these sweet ballet style shoes (regular price $19.99) for Mia.
Please note, this was my experience with two PayLess shoe stores in Calgary. I haven't researched their national (or international, for that matter) policy. YMMV!
