I just redeem a USD5 voucher using coins today. It is only after redemption and going into the voucher detail there is a mention of minimum order amount of USD50 requirement. There isn't such a requirement for USD10 voucher last I used. Those who are thinking of redeeming the USD5 voucher take note. Tiger should have been more upfront about this requirement. Already feedback to them but not sure they will do anything about it. It's like playing a game without knowing the rules in advance.
