<<Disclaimer: Verify this information before applying it to your situation.>> For those interested in knowing the responses to my question: Statistically speaking, 1/2 the replies basically said "don't waste my money" because ingredients change too often to rely solely on a listing. This group commented that reading the label each time was safest. The other 1/2 said "definitely worth the cost" because both lists are updated(more so when purchasing an upgrade) and these include manufacturer information. This group said that when in doubt of a product just call the number on the list. Also, a few persons said they'd ordered the Clan Thompson lists for the past 2 or 3 years. Opinions on PC version: more detailed than the pocket book. Too bulky to carry around a store. Opinions on Pocket Book version A fits well in a purse. Not detailed like PC version. Palm Handheld version: no comments received The following info and website was forwarded to me: (The Wheaton GF Support Group has a new list of GF drugs) www.napervillegi.com/celiac - follow the links low down on the page for FREE printable food/drug lists. Very thorough. Hope this helps fellow Celiacs decide on the listings! Celina * Please include your location in all posts about products *
