Autographs add value to objects, but careless signers run the risk of leaving signatures on the inside of baseball caps or over the first paragraphs of the Declaration of Independence. Score properly placed scribbles with today's Groupon: for $25, you get $50 worth of collectibles and autographed memorabilia with an $8.99 credit toward domestic ground shipping from Steiner Sports (a $58.99 total value).
Steiner Sports partners with a slew of professional and collegiate teams, including the San Francisco 49ers and Giants, to present fans with a plethora of authenticated sports collectibles. Niner fans can celebrate the historic franchise's resurgence by paying tribute to the past with a hand-signed 8"x10" photo of hall-of-famer Hugh McElhenny ($59.99). A handful of MLB-authenticated field dirt fills the 4"x6" Tim Lincecum plaque ($24.99), and a baseball used in a 2006 Mets versus Giants game ($39.99) lets buyers further cross-continental rivalries without spelling out taunts on a slice of New York–style pizza.
