For SPP, the subscription amounts are $1000, $2000, $5000, $10000, $15000, $20000, $25000, $30000. 2 years ago, $15000 is the max amount.
In the past, some "creative" people tried BPAYed more than once. Don't know their outcomes. Probably depended on if under-subscribed or not. I think someone may be desperate to try for this one.
