I love siw. IMHO it beats all the other system information tools (Everest, Astra, PC Doctor...). My opinion probably reflects the fact that I don't know about the real best ones.
I wanted to get the last version, so I went to its home page and found this.
I have seen and used other coupon sites, but this one is only for electronics, hardware and software and it seems to have up-to-date information.
It has three sections:
1) "Deals" which includes hardware and software coupons and deals
2) "TigerDirect Best Deals of The Week" IMHO Egghead and TigerDirect have the best deals on hardware (again, this may be due to incomplete information).
3) "The best Selling Electronics on Amazon.com". I don't like Amazon, but looking at bestsellers helps spot trends.
I don't know if this is widely known or helpful to anybody, but I am posting it anyway.
Cheers,
