Attempting to take advantage of the growing popularity of print-at-home coupons and airline tickets, CashStar Inc. is offering consumers the ability to print or e-mail customized gift cards purchased from a retailer's Web site. Uno Chicago Grill, Travelocity Incentives and Portland, Maine-based Gorham Bike & Ski started using CashStar's program last year. The Portland, Maine-based company says it is focused on signing up large retailers and restaurants during the next 12 months, according to CEO David Stone. Consumers can purchase an electronic gift card by visiting a participating retailer's Web site. CashStar's platform enables consumers to customize the look of the gift cards with personal messages and pictures, Stone says. "You're allowing a personal interaction between the purchaser and the recipient that you don't get with plastic cards," Stone says. CashStar is using Coupon.com's print barcode technology for its gift cards. Recipients can print the barcoded gift card, which the cashier would scan to redeem its value, Stone says. CashStar says it also is offering participating retailers the option to advertising on Coupons.com.
