That works great for most people, and I too have had some luck finding in store deals better than on-line. BUT, I don't have access to stores that everyone else does. In the town I live in (currently) there is 1 super wal-mart and 1 grocery store.
I have to drive more than an hour (and who can afford that these days) to get to a mall. So for some people these on-line deals really are worth it.
Just offering another opinion on the in store/online deals debate ....

PS ~ They do have some great deals, as does Kohls~a few weeks ago, I got my daughter a Columbia Sportswear Coat for $15.99
Great Deals to be had!
