Covid-19 Virus and N95

As if Jeff Bezos isn't already rich enough. As someone who is at high risk because of a compromised immune system, I thought it might be a good idea to get a few N95 masks. Because local medical supply stores are out of stock I checked Amazon. While the prices are reasonable (pack of 20 for $99), they want $200 for shipping. I bought some luggage a couple of years ago and because my order was over $35 the shipping was free. So how is it that something that weighs less than a box of Kleenex costs $200? Could this be a way of avoiding charges of price gouging? Keep the actual price reasonable but kill on shipping? If this is the case than Mr. Bezos could not only be the richest person alive but possibly also one of the most contemptible.
