Great topic. When do you all plan to give your recommender your gift? After they submitted all the recs? After you got in somewhere? Or both?
I figure I could do it now that my apps are done - but if I'm rejected by HBS, Kellogg and Chicago - my plan is to re-apply to Kellogg and Chicago on a part time basis. In which case, I need them to help one more time. Fortunately, I imagine they can submit very similar recs - the only critical difference being that I need one from my current manager for part time.
With that in mind, I'm planning on dishing out gifts after my acceptances - not before.
