Some things I’ve done:

Cut Netflix down to the one-at-a-time 9.95/month sub. That way we have a movie for Friday night, but not a pile of to-be-watched. Still cheaper and easier than renting at the store.

Cut down on RSS feeds, use Firefox Bookmarks feature Open in Tabs to build a user controlled read-on-the-weekends list. I have one for “New.” Sites really have to prove their worth to move from there to the feed.

Never buy more than one book or CD or DVD at a time. (One will always become your favorite and the others will be unjustly ignored.) Only buy DVDs of movies you’ve seen twice and would like to see again.
