"As a rule, surplus stores are mildly disreputable. They take the leftovers or discontinued items, which they purchase at a reduced price, or get for free, and resell them. Many dollar stores operate this way. American Science and Surplus is different. Their mission is narrow - they only accept surplus items that are - in some way - related to science. As their manifesto says, "we are fascinated by discovery and invention" and their ever-changing inventory reflects that." - Steven Perez from Bookmarklet
