With signup for a monthly subscription, Marvel Unlimited offers a 1-Month Online Comic Reading Subscription for 99 cents via coupon code "SDCC14". That's $9 off and tied with our March mention as the lowest price we've seen for a month of this online comic book service, which boasts 15,000 titles. Deal ends July 29.
After the promotion period, the subscription will continue for $9.99 per month. Note that this promo isn't valid with Annual or Annual Plus membership subscriptions.
