Makro Online faults

The online department is clueless. When you're trying point out the error nobody seems to understand. How I can Castrol 10w40 cost r449 in the store and online it is r1290? And when you Google online macro it shows r449 but when you go to pay it tells you to login in when you log in a new screen appears with nothing in the basket that when you search the product it does jumped up to r1290
