Too expensive

A bottle of Olof Berg Brandy cost's R90.00 in Vredendal Agri Mark Liqour and in Vanrhynsdorp Blue bottle liqour, the same brandy cost's R138.40!!!! How do you explain that?!!!! Maybe a 10 - 20 rand difference is acceptable but from R90.00 to R138.40. Isn't there a flat rate of pricing as this is a franchise?!!!! This is unexceptable and i think the owner of this liqour store is busy with *****!!!
