If it is a filter that we believe will eventually fit into our regular product line, we will ask you to purchase five and we will sell the other five. There will be no engineering fee. So if you round up some friends who want the same thing you want, it's pretty simple. We require payment in advance and our usual guarantee applies. If you want a filter that we do not believe will fit into our regular product line, you must buy ten.
Prices generally conform to our regular prices.
In either case, expect about ten weeks delivery for special orders. All Rights Reserved.
