Advertising confusion

i see on the websites of this company it had Duracell batteries From R799 and Atlas Bx from R699,i mean this is an adverti*****t on the websites and webmail domain.when you get to the store none of the two brands its anyway closer to the advertised priced.Duracell is at R1400 and AtlasBX R1200 its almost 50% of what they are advertised with even your partner tyger wheel at fourways crossing,why cant they be advertised with their real prices,is this marketing strategy gone wild.
