Do you need a Prime membership for Amazon's Spring Sale?Amazon's Big Spring Sale deals are open to anyone, even if you don't have a Prime membership. Non-Prime members may still need to meet order minimums (often $35) to unlock free shipping, and it probably won't be as quick as Prime shipping. If you're interested, you could sign up for one month of Amazon Prime for $14.99.
