Exchangers Price In Nigeria Too Expensive.

hi everyone,
i  came to notice that so many online Nigerians are quicly going into  xchange business, well thats a good development,but the only problem i envisaged, is the asking price , which i find quite exorbitant,i have taken time to check all the exchangers in Nigeria,i realise that all their prices are on the high side,and that alone tend to discourage many who want to buy digitals from them.i have stopped buying digitals from most of them, because its too expensive .
so guys what do u think about this trend!
