Jane, sorry for the delay in answering you, but I'm new to Hub pages. I'm not a White Zin drinker, so I'm not sure I can help you. If you live in California, I'm sure you're familiar with Trader Joe's, which has aggressive pricing on many items. Short of that, I would say Costco. White Zinfandel is a commodity wine subject to discounting in major stores and chains. Hope this helps.
