Do you ever buy your shoes online? It saves a lot of time going up and down the high street in search of the new shoes that you're after. And it's often also cheaper as well, since if you have a look around the net you may even find a sale on as well.
The only time I ever thought I'd made a mistake buying shoes over the internet was when I managed to snag avery decent pair of suede shoes at exactly half price - only to find out after ordering that they were in some kind of extra wide fitting. As it turned out though, they were absolutely fine.
Of course if you're really into your shoes online habit, then you may even buy collectors stuff from ebay. It's so easy to give in to temptation these days - all that retail is just a click away!
