While too many eyes are trained on Samsung Galaxy S4 at the moment, the tech giant is collaborating with Amazon to keep its outgoing flagships' brisk sales and the result - the Galaxy S3 now sells for a penny while the Galaxy Note flies away for as low as $US70.

The deals involve the three major telcos in the United States namely AT&T, Sprint and Verizon - all seemingly eager to toss out gadget offers that are to resist.

The best package is from Sprint with the telco boldly pushing the Galaxy S3 to Samsung device seekers. Buyers willing to be locked in a two-year contract can snap up the bestselling smartphone and they only need to fork out a cent or a measly $US0.01.

This is the cheapest way yet to own a superphone that only a year ago costs hundreds of dollars to get, which more than 40 million buyers around the world readily paid.

Simultaneously, Sprint is also aggressively pushing the 5.5-inch Galaxy Note 2 and among the U.S. network providers the company gives out the best phablet deal so far - a measly $US69 for the handset that wowed global consumers for its S-Pen and multi-tasking capabilities.

AT&T and Verizon are active participants too of the promo but it is the latter that may get your attention most. Verizon is luring Galaxy S3 fans with a $US0.01 price tag that of course comes with the usual plans. The company, however, skipped out on the Note 2 competition for now.

AT&T's price listing for both the S3 and the Note 2 is interesting enough. The company is offering the S3 for $US50 and the Note 2 for $US150.

Meanwhile, if you noticed that the price cutbacks have mostly affected the Galaxy S3, the explanation is simple: it will become a legacy handset soon in the immediate aftermath of the Galaxy S4 release.

However, Samsung is not about to neglect the phone as reports emerge that it is revamping its biggest device money-maker to date. The Asian tech giant will reportedly tweak the S3's screen, upgrade its battery and add up wireless charging to its already potent features.

The repackaging should be completed soon and likely will coincide with the expected April release of the Galaxy S4.

As for the Note 2, more price cuts will come its way, analysts said, as the release date of its replacement, the Galaxy Note 3, nears.
