Mossel bay McDonalds *****ing money

I would like to know why there is a price difference in exactly the same meals at the George outlet and Mossel bay outlet only +-40 km apart.I travel a lot between these towns and it is sometime now that I realised the difference.I bought a sausage egg mc****in meal at m/bay on Monday the 15th and paid R45 and on Friday the 19th it was R39 at George for EXACTLY the same meal .both with small orange juice.I think m bay mcd are *****ing money from customers
