Read the title as a question, my answer is YES.
For regular member, the membership fee is $55 a year. Including Business member and Gold Star member. There is no rebate for these membership account.
For Executive member, the membership fee is $110 a year. With 2% reward ( maximum $750 a year), and some Coupons for executive member only ( it gives more instance saving while shopping).
I am also using American Express Platinum Cash Rebate credit card which is issued with Costco Wholesale. It has up to 2% rebate(max $500). Note: No annual fee for it.
So it looks great. pay $55 more to get Costco Executive Membership and save more.
