I can't believe I'm having to explain this to you, of all people, but here it goes...
Where you went wrong was saying that while you had the money to buy one pedal, you were going to use your rewards to get the other.
What you should have said is that you would buy the one AND use the rewards for the other so you could get BOTH pedals. And then posted pics of both, links are optional but appreciated when used.
That's what any true TB'er would have done.
And to score even more points you could have taken the rewards your wife used for a purse, for yourself instead and got something else bass related.
*Disclaimer: I'm not a marriage counselor and I can't predict the outcome of this last option. Proceed at your own risk. But as a bass player, who's also divorced, I say go for it! She probably has enough purses already anyway.
Hope that clears things up for you
