My Seattle area Sam's (supermall location) has the Pine 16x CDRW retail box at $56. It is clearly marked on the shelf stocking box, so no price check is even needed.
As for memberships, at the EXIT doorway, they were handing out free "90-day" passes for us to give out to other people we knew. So, just look for a Sam's employee handing them out, get one, and then saunter in.... If no one at the exit is handing them out, just go to the customer service desk and tell them that a sam's club member told you about the 90-day passes being handed out, and could they please give you one because your friend (the sam's club member) didn't have it on him to give to you at that time he was bragging about Sam's club to ya....
