Consumers in the market for an iPhone 5S and looking to save some cash may want to check out the latest sales promotion from Best Buy.

The retailer is now offering the 16GB 5S for $125, a healthy discount from the regular price of $200. The sale price is good online and at Best Buy's physical stores. The deal is valid across Verizon Wireless, AT&T, and Sprint, and requires the usual two-year contract.

But you budget-minded folks won't want to wait. The sale is good only through Saturday, January 4.

Best Buy continues to offer the iPhone 5C for free. It also requires the standard two-year contract.
