Question about Ebay? Details inside?

I bought something off of Ebay. The person lives in Detroit, and my thinking was, my g/f and I would drive there to pick it up (it’s only an hour away). It is a chair, and the cost was 95 bucks. The seller had the shipping cost at 75. When I emailed the seller, I mentioned that I would pick it up. Perhaps, this weekend. I would give him the 95 dollars, then. This was a few days ago, and I haven’t heard from the seller. Maybe, they’re away, but, it looks as though they deal with people often through the week, as I see they leave feedback often. I am wondering if the guy (or lady) wanted to charge a bit extra for shipping??? Should I just wait a few days and see if they respond?
