Tottenham Hotspur have rejected a call to subsidise tickets for the Champions League final, reports BBC Sport.
But Spurs have declined, saying it would remove the incentive for Uefa to "price sensibly in the future".
Liverpool have not yet responded to the supporters' suggestion.
SOS and THST also asked the clubs to extend season ticket payment deadlines to allow fans time for another pay-day after the final, which Tottenham have agreed to.
The Champions League final takes place at Estadio Metropolitano in Madrid on Saturday 1 June at 20:00 BST.
Liverpool and Tottenham fans will share 33,226 tickets for the final, which takes place in a 68,000-capacity stadium.
Liverpool's season ticket payment deadline is currently 24 May, a week before the final.
