Everything I was about to purchase from Jet was more expensive than Amazon, even without prime. I unsubscribed from their emails and gave up with them.
There must be a heavy price difference depending on location because for me I was able to find many things that were 10% or more cheaper than Amazon. I ordered a blender for nearly half the price of the same model on Amazon for example.
Everything I looked at was technology or electronics. I don't really buy anything else on Amazon to be honest. You got an amazing deal though holy crap.
