They make you subscribe (vs purchasing just a single meal), which is very annoying and the reason I don't use them, but I've found them very easy to cancel. You just click a button online. And even better, they then send you a $60 coupon to rejoin a month later.
Sure, it's not like you have to call them, but all the ones I've tried have employed anti-patterns for cancelling meals and worse ones for cancelling subscriptions.
