Today is the Saveland draw for a great $50 Future Shop gift card. I also noticed that tomorrow is the draw for the $50 Costco cash card. I wanted to pass on what Noah told me in regards to the cash card: you do NOT need to be a member to use it!
The Costco cash card acts as your day pass into Costco. You are even allowed to exceed the cash card amount with no issue.
I hope that this clarifies the issue, and will now allow for non-Costco members to enter tomorrow's draw.
