Hi Shirley!
Welcome to the forum!
I must admit, I've never had the experience of my interest in an item causing the opening bid to jump! In that case, placing an opening bid would nail it down initially.
Your concern about placing that initial bid may obligate you to something that turns out to be something other than you expect, wouldn't that be a justification to withdraw a bid? Or maybe a better approach may be to put the item on your watch list and wait until ANOTHER bidder places the first bid before e-mailing questions?
