Lookup for the succeeding dates after the earliest date

[fbgail]

Hi everyone,

On the attached sample file, I used this array formula to lookup fo the "First purchase date" - {=MIN(IF((Sheet2!A:A=Sheet1!A2),Sheet2!B:B))}

However, for the "Second purchase" and "Third purchase", i'm stuck and can't think on how to return the dates.

Can anyone help me on this?

Thank you in advance!
