Rubber stamps are both integral to productivity and a work of art, much like motivational mimes and impressionistic spreadsheets. Celebrate dual purposes with today’s Groupon: for $15, you get $30 worth of rubber stamps, paper, and stamp supplies at Stamp Fanci.

Stamp Fanci slings rubber stamps and their necessary accessories to help beautify an envelope or make nearly any object instantly official. Thousands of stamp varieties ($2–$13) meet various inked needs, such as quickly dating handwritten letters or demonstrating approval of a child's significant other. A large selection of 8.5"x11" and 12"x12" paper ($0.30–$0.75) awaits writers and illustrators and inks ($4.50–$9) come in myriad colors and styles. Die-cutting machines ($80–$200) help creatives cut anything from paper to sheet metal. Like most high schools and kitchen cabinets, Stamp Fanci is closed on Wednesday and Sunday.
