I could still ship that size First Class. in a 24" x 6" x 6" Uline box for around $4.16 for 15 oz And most of the time they still get there the same time a Priority box would. I have shipped many to California on Friday/Saturday and they will be there Monday. And no extra price for the zones using First Class. Even more expensive items at $40. plus, with insurance is still cheaper than Priority in most cases. I check both ways to see which is cheaper. Box would be about $1.10 I buy on sale.
