They have them at Albertson's in Mira Mesa, last purchase was 2 for $5 with Albs card, bought 10. They also carry these a Johnathon's ($4.99). $6.50 is very high, do you recall what brand?
I don't recall the brand, but they did carry the seal from the Italian government. (just because they say San Marzano on the can doesn't mean they are real San Marzano tomatoes)
