Sears, Roebuck and Co. unveiled a major expansion of its Web business this morning. Consumers visiting sears.com can now apply for instant credit or purchase, online, a ‘Sears Gift Card’. Consumers can, upon approval, use their new credit line immediately to complete online tool purchases on sears.com. After customers receive their Sears Card in the mail, it can be used at approximately 3,000 Sears locations. The ‘Sears Gift Card’ can be purchased in $5 increments (with a minimum of $10, a maximum of $100) and may be applied toward in-store purchases at Sears store locations in the United States and Puerto Rico. For a limited time, there is no charge for shipping and handling when the card is purchased through sears.com. Shoppers may purchase Sears Gift Cards with a Sears Card, Sears Premier Card, Discover Card, American Express, VISA, MasterCard, Sears Commercial Card or JCB Card.
