If i bought duracell AA batteries from target or wal mart, how many times longer do you think they will last compared to panasonic AA batteries from a 99 cents store?
what if the panasonics were not alkaline?

Michael P gave a good answer. Panasonic alkalines are about as good as Duracell. But at a 99¢ store, you may actually be buying carbon-zinc batteries which will last only two-thirds to one-third, as long. Those are distinguishable because they do NOT say Alkaline on them, but instead say Industrial or Heavy Duty.
