Quoted from PinRob:$14.20 shipping, YIKES. That’s a bit of a stretch. I’ve shipped many tubes filled with complete cabinet decal sets for well under $10 clear across he United States.
That isn't unreasonable. Keep in mind that ebay takes 10% of the shipping price. Then also include the cost of packing materials & the label. Those aren't free.
So, after ebay's cut of $1.41, it's $12.79. USPS Medium flat rate is currently $12.80 with a discount.
