Strange that, for me in this digital era, I still manage to get many of the coupons I use via direct mail, i.e., my old fashioned steel mailbox: weekly coupon mags (dining coupons), coupon mailers (oil change), local store circulars (grocery).
I get a few coupons by email from office supply stores ~ $10/Off on $$.
I’ve checked a few of the ranking coupon sites but found it frustrating that so many coupons were out of date, etc. I’m still working on being a better online coupon finding guy. 
That’s my coupon gig.
Where or how do you get your favorite coupons?
Anyone here really good at getting your coupons "electronically"? Care to share the secrets of your success? (Don’t worry. I’m sure if you do share your secrets "they" – the coupon source – won’t run out of coupoons . . . unless there’s something else I don’t know.)
