Though this is true especially when buying large sums and/or using referral funds for large gc purchases, like 25k.
However, Lowe's Amex is an offer not a bonus and that's what the topic is on.
If a handful of peeps said the offer didn't trigger the cb AND a handful of others posted they had no issue, a Warning would be set for possible glitch. They would then need to call Amex to set things right.
And if a handful of peeps posted no dice, than a DP would be in place. Again neither of the scenario's have happened.
