Freecycle. I don't have a ton of extra money. I was so grateful when someone donated them.

I passed mine onto a friend, who passed it onto another friend. It's like the travelling pants of fertility lube and ovulation strips.

I have a bunch of extra (new, unopened) Clearblue OPK test sticks, ovulation test strips, and pregnancy test strips. Is there anywhere you can donate this type of thing? Maybe to women of fewer means who are TTC? I'm trying to downsize and throwing it all out seems like a huge waste.
