I buy almost everything online... I also use Schwanns to reduce the amount of trips to the grocery store :P If I had locally grocery store delivery service I'd use that as well! Time is money!
The only thing I don't really buy online is clothing/shoes/etc... unless it's a specific item and I already know it's going to fit the way I want.
EDIT: I use Amazon Prime for just about everything. I was hesitant at first but once you pay the up front "join" cost you end up using it a LOT more. One click shopping on Amazon, search for prime stuff... Free 2-day delivery... doesn't really get any easier! I probably save enough cash in just razor cartridges and batteries to pay for the yearly cost!
And as one more example. I needed to buy a wheelbarrow... couple hundred bucks at the local Lowes / Home Depot but I don't have a vehicle with enough space to transport it in so delivery is $60. I got to Amazon, grab a Fiskar's wheelbarrow at half the price with free two day delivery... membership paid for in one transaction
