but chances are you will have a better roi than your safe withdrawal rate of T-shirts and be able to leave a nice nest egg of t-shirts for your progeny.
This is a fairly likely scenario for me.
I have a ton of t-shirts, but most of them are either band t-shirts for bands no-one has ever heard of or freebies from cycling/running/triathlon races, so unlikely that the local charity shop would be able to sell them on.
Also, you know, it's not like I'm going to stop wearing t-shirts, so for now frugal me just tells wannabe-minimalist me to ignore the big box of them in the loft and pretend I've only got the ones in my drawers.
Haven't bought/acquired any for some time, but since my will-I-wear-this-in-public threshold isn't particularly high, I find it fairly hard to really wear them out - not long ago I went through and fixed a load where the seams were coming loose. I've had the same couple on gardening duty for a few years.
Pretty sure when they put me in a box I'll be wearing a shirt for a band that split up in 2008.
