There is something called Markdown Manager but I have never used it. Check it out on the Site Map (link at bottom of page).
Since you don't have a Store, you can't put your listings On Vacation.
With 95 listings a Store could be economical for you since fees are often lower. Look into it when you get back.
For the moment, your safest action is to close all your listings 24 hours before you leave home. The listings will stay in your Unsold Items list for up to 90 days.
When you get back , or 24 hours before you return if you have internet access, relist/sell similar all your 'unsold' items.
This way, although you do have to pay for the 'new' listings, you won't have any transactions you cannot complete promptly and all the fallout that can entail.
OOH!! Purses!
