Costco offers its members a $33 Costco Cash Card with the purchase of $100 or more in P&G products via this mail-in rebate. That's tied with our mention from about a month ago as the best discount we've seen on P&G items from Costco; for further comparison, we saw a $20 gift card offered, also last month. Rebate expires March 31.

Note: Allow six to eight weeks after close of program (May 1) for delivery of the cash card.
