How and where should I arrange pickup of an item?
If you are the one giving away items, it's up to you to decide when and where the pickup should take place. Often people will leave the items on their doorstep or arrange a meeting in a public place. You should arrange a time and place that works for you and the person you've chosen to come pickup the item.
How do I handle no-shows?
If you're offering an item and someone misses the arranged pickup, it's up to you how to handle it. Most people give the person a 2nd chance within a day or two before offering the item to the next person in line.
It's always a good idea to collect a few replies to your offers before marking them as gifted. This makes it easier to give away your item without having to repost.
How do items change hands - are they picked up or delivered?
Because items are being given away, it's expected that the person chosen to receive the item will travel and pickup the item. The pickup is done at a time and place that is arranged with the person offering the item.
