David, thank you for everything you do for this forum with your suggestions and valued information.I can't more highly recommend subscribing to UPS MyChoice which can automatically upgrade all Surepost packages to UPS Ground. $10-20 per year if you find an active promo code (sometime a Free Month or $3 for 3 month trial).
I bet I've had at least 20-30 packages over the last year upgraded. The service recently dropped from $40/yr to 15-20/year
