Amazon has lots more than books, so signup for Amazon prime. It's ~$80/yr but you can split it with up to 4 different accounts (so find some friends and it's $20/yr). Instead of all those trips to the store you can now use a few mins of your free time to order any items you need (batteries, shampoo, garbage bags - whatever) and they'll arrive within two days. Overnight orders are only $3.

Grocery delivery. Not a big fan of Safeway stores but their delivery is awesome. I get overwhelmed in grocery stores, buy things I don't really need, forget to buy others. Grocery shopping at home makes it very easy to compare your items and review your basket before finalizing your purchase. Works really well if you work at home and can schedule their 4hr delivery windows (cheaper).

Legal pads. Great for taking notes, sketching ideas, exploring ideas - lots of startupy tasks. They're high contrast and longer than traditional notepads. I know moleskins are generally the startupper standard, but give the legal pad a try one day.

Phonetag (http://www.phonetag.com/) I hated voicemail. Phonetag now handles all my voicemail, emailing me the transcription and MP3 of the audio. Now I can organize, sort and search my voicemail just as I do with the other items in my inbox.
