Surely a receipt or an invoice is the bare minimum they should do. Awfully scummy of them.
It's not a convenience question. Either they throw it away for you, or they put it in the bag and you throw it out yourself. Maybe even with the bag.
Then I realized, it could only be because they hope for you to agree to making the item no longer returnable. No receipt, no return. So you (potentially) only shoot yourself in the foot by saying no.
As you can see, LinkedIn have optimised the forgotten trial cancellation to a fine art.
1. Whenever you sign up for a free trial that requires a credit card, set yourself an out-of-band reminder for the deadline to cancel before being charged.
2. Every month, read through all of your monthly statements and make sure you recognize all of the charges on them.
