I am also real close to an Amazon Fulfillment Center (about 5 minutes away). But there are times where one can beat the prices on Amazon, and especially good to do if you are in no need to receive the item quickly. A very recent example for me is that when I was looking at this Samsung T7 1 TB SSD:
www.samsung.com
it was $149.99 on Amazon, but I found it on Newegg for $10 less (and that included free shipping). I know that Amazon will price match, but I did not want to get on the phone with them and go through that. Just ordered it from Newegg.
And there have been times I've ordered items through Amazon, but they will arrive anywhere from a day or two earlier than what they state. I suspect that's because I am so close to that fulfillment center.
