I found them reasonable at less than $8 per oem oil filter. If I remember right, I ordered 3 oil filters, a fuel filter , air filter ,gasket rings for oil pan plug, oh and almost forgot the notorious penion seal that I couldn't find anywhere else, and steering wheel badge .With shipping it was less than $84. Since I ordered multiple items the shipping was reasonable. This was last summer. It's a post on here about it somewhere.
However when I had just bought my machine, I ordered an oil filter from a dealer in Hattiesburg which is an hour from me and it was over $20 for a single oil filter with shipping.
