Frys deals with promos are useless to 99% of people. Generally it's a unique one time code specific to that email, and is for in store only. So I wouldn't ever consider these deals.
As someone who has a Fry's locally. You can go in and sign up to get a temporary code that same day, as well as being applied to the mailing list for further deals. Also, not all the deals are in store only. They work online as well, as long as the ad states online and in store. So saying their useless for 99% of people is a bit of a stretch.
