I don't know why the link keeps changing when I post it here. The link I copy from does NOT read currently unavailable but each time I try to post the link here it seems to take the user to a different listing that says unavailable!?! I just bought these, they are not unavailable!
The site does this automatically adding that tag. It's for site revenue. If anyone buys anything, a little money is kicked back here as a referral. Costs nothing extra. It doesn't show as unavailable to me.
I knew about the gmtnation tags but the odd thing is that everytime I clicked on the links I posted it took me to a listing which read "currently unavailable".
I usually don't bother putting them back. Unless some underhood gremlin actually pushes on the clip, this extra retainer is kinda useless. Click it in and tug to check positive retention. Extra lock not required.
