They do have sales on occasion, but I don't know that anyone but someone at Moss can say if they will have a better deal on Chrome WWs this year. Check out Little British Car Co. lbcarco.com they are a Moss reseller, and give an additional discount over Moss prices, even sale prices, and will even but an English biscuit in your package. Same stuff as Moss sells, they get it from Moss, just they offer an additional discount, they usually have cheaper shipping too, at least on small packages. Just use the Moss part number when ordering.
A true, and informative story if you end up dealing with them, I talked to one guy I know from my club who said he didn't like dealing with them because "you couldn't ever get hold of them" I said I got responses immediately from the guy, often even late at night, turns out my friend was calling and I was emailing, it is very much an electronic based business, and email works better as the communication method with Jeff the owner.
