Update: Just confirmed prices at the auto parts place. Went in there to grab a bottle of brake fluid, and the oil and filters were right next to that. $11-15 for filters, cheapest oil was $30 for 5 quarts on sale! Regular was alot more than that (around $40). Plus the shelves were about 1/2 empty!
I remember walking into that same store just a few years ago and could get a 5 quart jug with filter for $22. Now that's close to $50 unless they run a special.
