If you cancel the free trial as soon as you start it you normally still get the full trial so nothing to remember!
Shoutout to Shudder, a streaming service for horror movies/shows, that doesn’t confirm payment at all besides making sure it’s a real card.
I’ve been using 10minute email and a gift card with 13 cents on it to make free trial accounts for more than half a year work no issues
you don’t even need gift cards, you can make valid cards if you follow the luhn algorithm, look it up there are generators online
And that’s why companies don’t let you do this lol. Only a matter of time for Shudder to be harmed by this practice and change it.
With Amazon at least you can contact them and ask for a refund if it’s just one or two days after the payment, it has worked twice for me (genuine mistakes of mine)
