Ever had an unexplained Paypal charge? Most likely it was due to having a subscription, trial or pre-approved payment that has renewed. It’s worth checking occasionally to see what is setup on your account and cancel any you don’t want to pay. This is extremely important when signing up to things like free trials etc

or go to Paypal > Login > Settings (cog top right) > ‘Pre Approved payments’ (bottom right of settings page).
NOTE: You will probably see things like Skype, eBay etc be careful cancelling those as they’re most likely NOT subscriptions but are pre-approved payments (similar to a Direct Debit at your bank).
You should also do the same for Direct Debits/Standing orders at your bank, most online banking websites let you check these.
