I really, really, really hope that adven/merissa are right and that she thinks it's worth more than that.
but then the other part of me thinks if she really thinks you deserve more, she would just give you more than the $45 and be done with it.
I quoted a coworker $62 for cupcakes a few months ago and she loved them so much, she gave $75 - no research involved. If you think someone deserves more, you give more. If I love a waiter's service, i give more than the standard, I don't have to go research it first.
Just let us know when we can saddle up and research her behind.
I do hope you at least get your $45 soon! Anything less than that would be a slap in the face.
