I was offered spend $x amount for for 4 weeks and get 10000 bonus points. I completed my week 1 shopping and into my 2nd week. All of sudden, the offer is expired. I called flybuys and CS told me that's normal. The offer expired after week 1 so I can't activate it again. I politely told him that from my past experiences, the offers always stayed active for 4 weeks, and i'm not going to spend a cent if it says expired. The CS insisted there's nothing wrong with their system. So I guess it's time to say goodbye to flybuys.
