I'm interested in buying something. Person x else wants to sell thing.
Great.
We check and discover that we both have same weekend free. I can come and take a shufti at thing this weekend.
Arrange my life to have car, roofrack etc for this weekend. Message Person x to arrange time and day.

They are 60 miles away. They have been trying to sell thing for 2 months. This is the only weekend for weeks when I will have car and time. FFS.
It's still a couple of days until the weekend ...
Depending on the tenor of the previous conversations, if I were the seller and the weekend had been agreed, I wouldn't necessarily be too bothered about narrowing down a time until Friday (or maybe even Saturday morning), at least as long as I was able to be flexible.
Sure, if I could only make a particular two hour slot on Saturday night and an hour at lunchtime on Sunday I'd have been keen to check that one of those worked for you, but if I knew I was going to be around all day I'd probably be happy with leaving you to give me a call before leaving, to see if I would be around in a couple of hours time.
I do realise some people might feel I'm a little lackadaisical ...
