No problem, I pick up extra filters all the time, I've sent maybe 40 filters to 53' Stude over the past couple years and finally decided to cut some myself. Used filters are going to be cut in the near future.
I figured for the ~$2 each, it would be a nice "investment" for the board, since it seems many people talk the talk of extended OCIs and premium everything, but most do not walk the walk, and use "less than premium" filters and oils, since they've been proven to work just fine in daily drivers. This way, at least you've seen the inside of what these inexpensive filters have to offer, and can make informed decisions to run a 5k OCI for less than $15 with tax, out the door. Plus, you'll be keeping local folks with an actual retail job vs. just buying online!
