For general sales, you may want the newsgroup misc.forsale.non-computer (news:misc.forsale.non-computer) or a group that ends in .forsale or .marketplace.
If you want to find a place to advertise or sell more specific items, you should NOT post them to any and every newsgroup available to you.
Many hierarchies have separate groups for buying/selling/advertising, or have special restrictions on what types of ads can be posted to a group and how often they can be posted there. Your best bet is to ask the members of the newsgroup whether advertisements are permitted in their group, and where ads or sales posts could be posted instead. If you are polite, the readers will be more than happy to help you out!
