Anymore the wirebacked microglass filters from everyone are around $15, Royal Purple are a buck cheaper from Royal Purple direct if you want to buy bulk and buy enough to get free shipping, but $13 is the new normal for a filter like this, it's still cheaper than a Royal Purple or Amsoil when buying small quantities and it's essentially the same filter, I'd probably just use both of them and cut them up once you've used them, we've already seen what they look like on the inside and $13 is a little steep just to throw it away.
