Inspired by blankedboy's deal I thought I'd check and see if Marvel Unlimited (online comics) is on sale again.
Lo and behold, it is in time for the Black Panther movie. usual annual subscription is $69 so not that big of a discount ($5 x 12 months = $60)
Unfortunately doesn't apply to the "Annual Plus" subscription.
I haven't used it for a while so i'm unsure how much of a delay there is (if there still exists one) between the print copy and online so this link may not apply.
Also, here's a handy link that should help with reading orders and such.
and based on blogs regarding "is Marvel Unlimited worth it" - it does appear to be so
