Share Purchase Plans - Can You Keep the Shares?

The ASX rules that you can't buy less than 500 dollars so fair enough when it dips below 500 a day you're allowed to keep them. A lot of companies offer what's called a small parcel share sale facility which is an inconvenience for those who have lots of tiny shareholders. So unless you tick the box and return the form back and say I don't want you to buy them back you'll probably end up with a small check in the mail later on for that. They scoop them up do they really?
