Nope, I would rather ask the question and be thought silly then deny the seller a sale because of ignorance.
I was weighing the cost with the information I have as a seller, what I sold (which was not very small items), how much my shipping materials cost and postage. I have also been out of the selling game for 3+ years.
In my realm one dime, one padded envelope, possibly card board for structure, labels, ink, etc. I could not get to $2.00. Once someone explained some of the finer details I was missing the postage made sense.
Which is why I asked for someone in the know to explain.
