Today only, ThinkGeek offers free shipping with no minimum purchase required. That's the first free shipping offer we've seen from ThinkGeek this year. Some exclusions may apply.
A best bet is this Star Trek Enterprise Pizza Cutter for $17.01 with free shipping. That's $5 under our mention from last December and the lowest total price we could find now by $2. It's modeled after the NCC-1701 Enterprise (from the original Star Trek series) and features a laser etched stainless steel blade.
