Thrifty competitor (5)
I believe the answer is:
alamo
'thrifty competitor' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for alamo that I've seen before include "Where Davy Crockett met his end" , "Site of 1836 massacre in Texas" , "Texas fort, scene of famous siege by Mexican army" , "Where Davy Crockett died, 1836" , "The --, Texan mission besieged in 1836" .)
