I offered someone a box on Monday and haven't heard anything yet. I realize it's summer and a holiday week so I thought I would wait until at least the end of next week and then pm if I haven't heard anything.

Bob offers don't "time out" do they?

No, they don't time out. I would give the other person a few days more to respond and then cancel and order the books from someone else.

Or you could let it sit there till it starts to drive you nuts.  If PMing them doesn't do the trick, then you would have to contact R& Co. to cancel that order.  I had one listed for over a year......................

Thanks ladies.

Wow, that's incredible. Could you not click on the "decline offer" link to cancel it? That was what I was planning to do next week.
