well just to clarify ..lol
one centre 100% $60 per day gap= $18.03
2nd centre 100% %55.50 per day gap = $9.39
so based on same percentage you would assume second centre would cost $13.50
im thinking maybe one centre is charging 11 hours and another 12? could that be the difference?
sorry to confuse! and i should so be asleep!!
