dark_angel104,
You are correct that the Escalon website only allows purchase online of the 6-In-1s and the Bella Rossa. I don't know where you are located at the moment, and whether Escalon ships to Mexico, but you should be able to get the other Escalon brands from a distributor of foodservice company. If you are in the U.S., I believe you may be able to purchase some of the other Escalon brands, including the Bonta and the Cristina, from PennMac, at
http://www.pennmac.com. You will see some Escalon products at the PennMac website under the "Pizza Makers" tab at the top of the homepage to the right, but PennMac sells many other products that are not shown on their website. You may want to call PennMac at 412-471-8330 or 1-800-223-5928 and ask to speak with Rose. She is a member of the forum and should be able to tell you what Escalon products PennMac sells. I think you will find that the Bonta and Cristina tomatoes are sold only in #10 size cans. A #10 can holds just under 7 pounds of tomatoes. A typical price at PennMac is around $5, but Rose should be able to tell you specific prices for the brands you are looking for.
I was able to find pizza recipes at the Escalon site using the Bella Rosa for pizzas but not for pizza sauces. I used the pull down boxes on the recipe page to find the recipes.
