+### Robux e Tix

+Moedas **virtuais** (sem dinheiro de verdade). Todo dia de login rende T$ 10, e membros do Builders Club ganham também o salário diário de Robux (BC 15, TBC 35, OBC 60). No catálogo, o item custa R$ preço ou T$ preço x 10. O saldo aparece no topo; a página `Money.aspx` mostra o saldo e, para admin, permite dar ou tirar saldo de um usuário.
