One of last year’s big holiday contests was the “Starbucks for Life,” a giveaway that would eventually grant some very lucky Starbucks cardholders one free item per day for 30 years.
This year’s “Starbucks for Life” sweepstakes, which runs until January 11, again offers 30 years of free coffee, but adds a new twist: there is a game that customers must play if they hope to win the prize. Last year 14 customers -10 in the U.S., three in Canada and one in the UK – won the grand prize of Starbucks for Life in the “It’s a Wonderful Card” sweepstakes last holiday. The estimated value of the ultimate prize in the U.S. was $54,000, and it included an engraved card made of 10K hammered gold. This year, however, only five participants in the U.S. will take home the grand prize during this holiday season’s contest. However, competing in the sweepstakes will also make you eligible to win Starbucks for a year, Starbucks for a month and Starbucks for a week.
