I recently visited a new NAPA in Whitby. I went in to check out their NAPA Gold filters, and was about to buy a few and then took a look at the cut open Spinflow filter. I was looking at a 3148 Napa Gold which was about 8 or 9 dollars. If I bought 12 I can save 0.50 each. The Spinflow is on special for 3.22 each.
