Alternatives to Amazon.com?

Although we spend a ton at Amazon, I've found that they aren't the best deal many times especially if I don't need the product in 2 days. Here are some alternatives that I use. Share yours too!

bhphoto.com - Camera and computer gear as well as plenty of Apple products.
albeebaby.com - Car seats and other baby products
rainbowresource.com - Educational books/products
jacobsroom.com - Melissa and Doug products
ajmadison.com - Appliances

Newegg is usually competitive with Amazon prices. Although before when I ordered it would come from their City of Industry location in a couple days. I just ordered a hard disk and it appears to be taking days cause it's coming from Illinois. Not sure it's worth the $3 savings over amazon prime, I would have the drive by now.

I think that Google Express can be a competitor to Prime when it becomes available around here.
