So who in the Boise area was able to score on some NAPA conventional and synthetic? The price was a walk in retail customer deal. Conventional was 99 cents for conventional and $1.99 for synthetic. I bought the two case maximum 5w30 synthetic. I just could not pass up on that price at all. It beat Walmarts price on even the Supertech all to bits. If you missed this sale there is supposed to be another one next month on the second Saturday. NAPA is doing it to generate customers to come to them instead of O'Riely or Autozone. The sales person told me about the sale when I went in Friday morning to pick up a brake switch and wiring harness for my F150.
