Walmart has implemented a limited-scope program for nearly 100 generic drugs (with multiple drug/dose combinations) offered at a $4 price for a 30-day supply in most states. Most drugs on the list may also be purchased at $10 for a 90-day supply. Available in all states except North Dakota. However: Due to FAIR PRICING laws in CA and MN, many drugs will carry higher prices, or may not be available. Other states previously listed with possibly higher prices, included HI, MT, PA, TN, WI and WY. Prices apply to Sam’s Club pharmacies also. Revised price list dated Nov. 2018.
