I purchased 2 jugs of PU about three weeks ago at Walmart. At check out I paid for them separately so I would have a receipt with only the PU on it.
The caps were sealed but when I checked after getting home they had no codes. Instead of returning them I submitted the code request via the FRN site. I received an email with the codes without issue last week.
Perhaps they have worked through their problems with issuing missing codes.
As long as you're not trying for the $10 rebate AND a missing code (Meijer, Menards, etc.), you'll be OK.
