I buy almost everything on line. Even food when the shipping is free, although I like browsing the aisles in person better.
If I buy clothes, I tend to use LandsEnd because I know how their clothes fit and only missized something once and returned it with no problem. I never had a problem with shoes either. I buy my aunt's clothes for use in the nursing home from cheap catalogues. We buy almost all of our computer gear and techie stuff online too. Ordering stuff on line is about as computer smart as I get!!!
