Ten charities are competing and campaigning for online votes from Facebook members, with the final tally determining which nonprofits deserve the biggest slices of $3 million from Minneapolis-based Target.

Bullseye Gives is a two-week-long giving campaign that started Sunday and runs through May 25.

Target, long known for giving a portion of its sales to charity, is asking Facebook members to visit www.facebook.com/Target and help decide how the 10 national charities will divide the retail giant's $3 million in weekly charitable giving.

Those 10 charities are: the American Red Cross, the National Park Foundation, the Breast Cancer Research Foundation, Operation Gratitude, Feeding America, the Parent Teacher Association, HandsOn Network/Points of Light Institute, the St. Jude Children's Research Hospital, the Kids In Need Foundation and the Salvation Army.

The larger the percentage of votes, the more each organization gets out of the $3 million.

Voting returns and dollars allocated will be updated in real time at www.facebook.com/Target. Site visitors can vote once per day, every day throughout the contest. Final results will be announced May 26.

The roster of 10 was built in order to offer the public a variety of charity sizes, a varying levels of reach and a broad scope of missions they pursue, said Target spokeswoman Kelly Basgen.

Some of the 10 already have a relationship with Target, but the money raised in this effort "will be above and beyond" what those charities typically receive, Basgen said.

The Salvation Army's national spokeswoman said that accepting Target's offer to be one of the 10 charities was "a no-brainer."
