I recently bought some Scarpetta pasta sauce on Amazon for $18.93 - 20.27 for a 4-pack (20 oz. each, for a total of 80 oz.). They sell this sauce fresh at Whole Foods for $6.99/jar (under the name Sauces 'n Love). I tried it today, and it's excellent - it has a fresh flavor, a thick but not chunky consistency, and a nice flavor balance. There's Tuscan vodka, Puttanesca, Barely Bolognese, and Arrabiata. Of course, if you meet the $25 threshold, shipping is free.
Before anyone asks: I do not work for Amazon. Nor do I work for eBay.
Cheers,
Molly
