I first tried soymilk earlier this year. The grocery had it on sale and I had an in-store coupon for $1-something off. I think I paid less than a dollar for it. I didn't like it, as I had the plain. I ended up mixing it with regular milk.
I completely switched to soy a couple of weeks ago. After trying Trader Joe's quart vanilla (YUM), I started buying Silk because the quarts, unrefrigerated on the shelf, were "only" $1.69. I liked it. After the second quart, it occured to me that maybe I wasn't getting the best price. The next time I went to the grocery store, I divided the servings of the quarts by the price and the servings of the Naturally Preferred Soymilk by the $2.69 price. The half gallon turned out to be cheaper per serving by a dime. I actually like the Naturally Preferred taste better. It's got a nice, sweet vanilla taste to it, that would be good with smoothies or milk shakes. (Okay. I'm still eating ice cream.) I told my husbnad he would like it, but I don't thin he's tried it.
In my fridge now I have a half gallon of 8th Contenent Soymilk, vanilla, light. It was on sale for $2.69 (reg. $2.99) and I had a $.35 coupon that doubled to $.70. So for $2, it's worth it. Unless I have a coupon for 8th Contenent (they're in the Sunday paper regularly), I'll continue to by Naturally Preferred, unless somethingat Trader Joe's is cheaper.
Sorry for the rambling.
