I also tend to buy things from Amazon simply because of Prime. I've used the cheap next-day and Saturday delivery options a lot as well. It really comes in handy when you're in a pinch.

I only learned about this a couple months ago, but you can share your Prime membership with up to four "family members" for free. So, you could potentially split the cost between friends and family. Just FYI...
