6 quarts, Amazon has a subscribe and save program and I'll get a case of six every 6 months. We are on a low carb diet (well, sort of) and she looks for hidden chips and candy the daughter stashes. I got 6 quarts coming for $30.34 and then it should be $36.02 after the first promo price expires. Even if the promo expires, regular price is $37.92. Cheaper than the local parts place and they have to order it. They want $6.69/quart ($40.14 for 6).
