Always use a virtual credit card for subscriptions.
I think we're headed for a world where we have to pay a monthly subscription to breathe air. Maybe that is what taxes are... Anyways there is a way to help make sure your monthly expenses don't get out of hand - use a virtual credit card on privacy.com for each and every monthly subscription. Here's the two most common games that companies play:
1) Hide the fact that the price you see now is not the one they're going to charge you long term.
2) Make canceling subscriptions so difficult that you give up and keep paying till your card expires.
You can win at both of these games with a virtual credit card. Privacy allows you to set a monthly or yearly spend limit on each virtual card you create. This helps you avoid any services that automatically jack the price up higher than you expect. For services that make it hard to cancel your subscription you can simply pause or delete the virtual card.
