Long story short, my idea was that it's possible that many here are in a similar situation. We can take advantage of USPS flatrate boxes and exchange trash for treasure. (Shipping internationally is not worth the cost and hassle for me.)
Here's my list. Category 1 is stuff that has some value ($30+) I have that I'd exchange for approximately equal value. Category 2 is extras that I don't bother to count the value of. The wanted category is stuff I'm currently on the lookout for but if it's not on there, I might be interested anyway.
To join the fun either PM me with details or list your own categories.
