Are there any legit sites you have found for subscription discounts/deals?

Following on from my post on cancelling to get discounts, I've been racking my brain on this.

I know dea' sites are widely available for business SAAS, but are there any you use/have found for regular consumer subs?
I mean legit ones, not those weird dodgy ones where they try sell you part of a family pack.

So far there are the student discount sites (need to be a college student), Coupon sites (sometimes these works sometimes not), and rakuten/honey but they seem to be more online shopping/cashback orientated.
