1. Selection, selection, selection. No more hunting for my size. I look at patterns and buy my size. 2. No shortages in my size. Usually plenty in stock even in half sizes at the right store. When you're small these don't hold true. Good luck finding a selection of pants at W30 and smaller. Some stores have stopped stocking smalls and shoes smaller than size 8. Some manufacturers have even stop making size small. Things are better in large cities, but not invariably I'll find tons of things that I like in that aren't in my size. One quickly starts cringing at the familiar refrain of 'Oh. We can order it for you." For me, online shopping is not just about price, it's about choice.
