Plugin to allow for recurrent subscription + exclusive content

Recently my step-mom lost her freelancing gig with a couple of newspapers. She ran a fairly prominent feature about two shows, and decided to take her writing elsewhere, setting up her own website to use.

She did some initial probing of her userbase and they all said they’d be willing to pay $5 or so a month to be able to read the stuff that my step-mom writes, but obviously we don’t want for these posts to be viewable to anyone outside of the subscribers or herself.

Anyone here use anything? I’ve seen something to do with woocommerce pop up, and quite a few other places that charge a good bit to be used, but I have no experience with them so I’m hesitant to commit to one I have no feedback about.

Thanks in advanced!
