20 MCR points, plus McBites coupon is 20 points = free

There are still two codes working (reset daily around 8 PM) that add 10 points each to your My Coke Rewards account.  They are:

10096122897198 
10096071476917  no longer working as of 8/8

The McBites coupon is 20 points, 4 more days, so add your points in and snag the free McBites if you haven't already.  It does not seem to indicate a limit, but the coupons expire 8/31, so they will likely ship super fast, but you won't have a long time to use them.
