Thank you for this. I was in this exact position once, where a better offer came along just after I had accepted. Honestly, if the original company had matched (or gotten very close to) the better offer I would have still gone there since it wouldn't have required moving. But it was so much higher that I knew it was basically not going to happen. I felt guilty about that for a while. But going to the company I did turned out great for me, and if I was in that position again I'd do the same thing.
