Our Verdict
Costco Executive members get $10 each month discount on orders of $150+ from consumer Costco-Same-Day or Instacart. This deal we’re discussing here is a separate deal which offers all Costco members $10 off $35 from Costco Same Day from 7/27 – 8/23. I’m not sure if this one will work on Instacart too.
