Costco Executive Membership (2%) Rebate Check

This is my Costco executive card 2% rebate check this year. 
$104.99 means I spent $5,249.50 at Costco last year.

Basic membership is $55.00/year
Executive membership is $110/year.

So, I need to receive $55.00 rebate check to cover my executive membership fee.  With this rebate check, I am getting paid $49.99 to be an executive member.

But, this is not the only check I will receive this year.  There is Costco/AmEx back check coming up.  I have about $270.00 there.
