I set up a prepaid cremation plan with
Baldwin Brothers online. Picked my desired options and never had to speak to anyone or listen to a sales pitch. It was $795. They sent me a certificate and I gave it to my executor.
It was great for me, as someone who doesn't believe in expensive funerals (and only has two close relatives), but of course others may want a more personal experience and you can always go meet with them in person.
