Speaking of Aliexpress.com, a week ago I was told about these spring loaded guitar picks by one of our Anons. Very appreciative of that still by the way...thank you again...Now, I found a listing for the Black Mountain spring loaded guitar picks on there. These prices are CAD so may be cheaper in your currency.

Cheaper than buying directly from the Black Mountain website. But they are still not an inexpensive pick. But probably worth it. I've not ordered mine yet but will soon.
