Here's the problem with shipping quotes.
You don't exactly know what it's going to cost, until you get to the post office. For this reason, I don't charge for shipping at all. To get a quote for your stuff, Texas would have to go to the post office with the stuff, weigh it, get a quote, go back to their office with your stuff and then send you a quote.
They might be able to give you an estimate (depending on what the stuff is) but you never know until you get to the post office: it's a "crap shoot."
Just pay the shipping and make it easy on 'em!
