Bitcoin is safe, simple, cheap, and most importantly, secure. Companies that accept Bitcoin show that they care about their customers. The problem with the current online transactions are the massive transaction fees that are charged. When Paypal or a credit card is used, massive transaction fees are charged. Accepting Bitcoin presents the option of cutting out the middleman for everybody. There is no risk for either party (the consumer or the distributor) when using Bitcoin. If Amazon.com follows the example of Overstock.com, then all Bitcoin transactions will be instantly transferred from Bitcoin to USD (or whatever currency).
Bitcoin Offers:

Low transaction costs 

Decentralized currency

Low Inflation (Because of the finite supply of Bitcoins (this mostly benefits the consumer))

Bitcoin is accessible to any person of any age, sex, demographic, etc. (it is extremely advantageous to citizens of crisis countries)

Non-reversible payments (Extremely beneficial to reputable companies such as Amazon.com)

Bitcoins are extremely secure (Bitcoins reside in an encrypted format on the wallet they are kept in)

Add in the fact that Amazon will become the first E-commerce company to implement the lightning network...now that's history!

Overall, it is a complete and necessary courtesy for Amazon.com to accept Bitcoins from their consumers. Help us.
