How come most of the host here round up to Rm100? The total cost for 6 slots is only Rm502.8 which translates to Rm83.8 per person. I can understand if it's in the range of Rm84 to Rm85. There is no additional work involve except to add/remove members, collect payment on time and maintain monthly payment.
No offence to all hosts, just asking.

Isn't it host can invite up to five family members, totaling six users?
