Thank you both for your reply. I walked into my local Kubota dealer today and asked him about the 10% off K filter sale and he looked at me like I had three heads. He's never heard of the sale. Now I'm not saying you are wrong, as my local dealer (5 miles away) isn't much. I had to wake the guy up at 11 am to ask him for a price on an L47TLB. He "put me on a list", I was at the bottom of the second page on a legal pad, two columns of names and phone numbers on each page. I noticed that you are from Canada. Perhaps it is a Canada only discount?
When I asked him for a ballpark price, his reply was "a few thousand off of MSRP, and I had an approximate 2 year wait time.
Needless to say, I'd pay shipping on a part before I will spend a dime in their dealership. I thought if Kubota sold a filter "package" I may save a bit by buying them all at once.
Thank you again for your help.
