I always find it amusing when sellers list used items for sale that are still available new.
protectxyaneck has done that very thing. He’s listing this Triple B Records shirt that was first released last fall (Fall 09, 90% sure), which is still available today.
Now, perhaps you don’t mind a used tee. I’m not against them. I have plenty of them. But most of my used tees are over 5 years old. Not under 5 months.
Then again, perhaps you are looking to save a few bucks. If you live in the US, the new Triple B logo shirt would cost you $12 shipped, the used one could be as cheap as $9 ($5 shipped first class for a tshirt is pretty much highway robbery. That’s the cost of priority, really).
So you decide. New shirt for $12. Or the used shirt for (potentially) $8.99.
