If you find stuff that you don't really need or want, you might want to grab it anyway, and try to sell it. Most shops in town will give you a maximum of half the retail rate for an item in good shape, or a lot less if it is heavily used. A lot of times they will just not be interested at all in buying back common stuff.

Rare items might not have a fixed retail value, so you will need to bargain with shop owners.

Of course, you can always skip the middle man, and try to find that collector of rare items that will pay top dollar for what you have - good luck - that may be a whole other adventure.
