You're not the only veteran that doesn't have daily payouts. Why Amazon would introduce such a feature only to new sellers is beyond me; it's as bad as the cable company giving new customers a price 70% lower than the best price they'll give me. But I see no signs that the current situation will ever change.

But a word of warning; be very careful to keep your account separate from your son's (you probably already know this, but worth repeating). If he lives with you, then the accounts are linked, but if not, be sure you never check your account from his computer, or vice-versa.
