I always go into my account and turn off auto-renew immediately. But this is the worst - my husband paid a PayPal monthly fee for an unused Flickr account until I noticed like 20 years later!!!
Just wait for someone to try to steal money out of your debit or credit card account, be forced to freeze the accounts and cancel the cards, then auto renewals take care of themselves. Happens to me at least one per year.
I tried to cancel Vanity Fair and they make it so difficult. Then I forget about it because I don't actually get the physical magazine. Then I'm charged.
I have all my subscriptions listed in a spreadsheet so I can see when renewal dates are approaching. Since I keep my other financials in the same spreadsheet im always looking at things pretty regularly.
I was just charged $80 via Paypal for an auto renewal for a subscription to Bon Appetit. I am so mad I didn't cancel in time but had no idea after 20 years of subscribing it would get so expensive. How do you stay on top of auto renewals? I need to find a better way.
