That's very funny!
I recently went down to a LCS. They're selling at 30% HiBV. They negotiate. I get to see what I'm buying. I have no shipping costs at all - but there's sales tax, which could end up being the same. I don't have to wait for 3 months or 6 months for delivery. I don't have to get pissed off when the cards show up with dings or creases the trader didn't announce. Of course, it depends what they've got in store. But I'm beginning to feel like it may be the most satisfying method.
If we had a decent LCS in our area, would most definitely spend a bunch of time/money there.
In regards to shipping costs -- anything that can go in a PWE, I charge $1.00 for. That covers the $0.75 postage, the penny sleeve, the hard sleeve, the envelope and the gas to get to the PO. Anything bubble mailer, I charge $4.50 for, which covers all the same things.
