You should consult a lawyer before you sign up for things like this. You apparently did not read the terms and conditions for Prime shipping and the general guaranteed shipping terms and conditions for all Amazon shipping.
And the Amazon Conditions of Usecontain the following under Disclaimer of Warranties and limitations of Liability:
THE AMAZON SERVICES AND ALL INFORMATION, CONTENT, MATERIALS, PRODUCTS (INCLUDING SOFTWARE) AND OTHER SERVICES INCLUDED ON OR OTHERWISE MADE AVAILABLE TO YOU THROUGH THE AMAZON SERVICES ARE PROVIDED BY AMAZON ON AN “AS IS” AND “AS AVAILABLE” BASIS, UNLESS OTHERWISE SPECIFIED IN WRITING. AMAZON MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, AS TO THE OPERATION OF THE AMAZON SERVICES, OR THE INFORMATION, CONTENT, MATERIALS, PRODUCTS (INCLUDING SOFTWARE) OR OTHER SERVICES INCLUDED ON OR OTHERWISE MADE AVAILABLE TO YOU THROUGH THE AMAZON SERVICES, UNLESS OTHERWISE SPECIFIED IN WRITING. YOU EXPRESSLY AGREE THAT YOUR USE OF THE AMAZON SERVICES IS AT YOUR SOLE RISK.
To provide some quotes (though the entire set of terms and conditions really ought to be read by someone competent in contracts):
Amazon Prime shipping:
Prime shipping benefits depend upon inventory availability, order deadlines, and in some cases the shipping address.
Amazon Guaranteed Shipping exceptions to refunds:
The guarantee does not apply if we miss our promised delivery date because of an unforeseen circumstance outside of our control, such as a strike, natural disaster, or severe winter storm. Also, delivery scans might be inaccurate.
So in summary:
Unless it is promised at the time of purchase, there is no guaranteed two day delivery.
Even if it is promised at purchase, there is no warranty of the Amazon delivery service.
You can get a refund on shipping charges (as a Prime member your refund would be the full $0.00 you paid for two-day shipping) but you would have to show that the current crisis is not an unforeseen circumstance outside of Amazon’s control.
I think they might have employed some good lawyers to write their terms and conditions for Prime and for general use of Amazon. Just maybe?
