Target on Monday lowered the threshold for free shipping on online orders to $25, making it among the most competitive among major retailers. Its previous free-shipping minimum was $50, which placed it in the higher end of the spectrum. Amazon.com offers free shipping on orders above $35, and offers free two-day delivery for customers who buy a subscription to its Amazon Prime service. Wal-Mart offers free shipping on orders of $50 or more. Many retailers, including Target, temporally suspend those minimums for the holiday shopping season.
