Not only what hotrodhandyman said, but Ecklers sale prices often only match others' regular prices. And since they don't manufacture anything, it's always available somewhere else. Often at a better price where they will tell you if it's in stock before you order, etc., etc. Shipping charges are an issue too.
I used to like to have their printed catalogs - just to see what things look like and what's on the market - but I quit that a few years ago too.
