Place not available in selection? Me too (4)
I believe the answer is:
same
'me too' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for same that I've seen before include "Equal in amount or value" , "Identical or similar" , "If - be the food of love, play on (Twelfth Night)" , "Aforesaid" , "uniform" .)
