OMG!! our formal rush budget is only $500!! as for who spends the most $$ on rush for sororities- every house should be spending the same- it is supposed to be restricted by panhellenic. hello- NO FRILLS??!! COB rush $$ is entirely different though. i don't know who would be the wealthiest sorority on our campus- we all have houses, i would hasten a guess to be Alpha Phi or Kappa Kappa Gamma. (however, $$ isn't everything, they aren't in the top 3 in terms of members!!)
oh, as for highest dues- definitely Tridelta or Kappa.
