Incorrect prices charged

This has happened to me a few times, where products are marked at a certain price and then, upon check out, the prices are incorrect and more so, they are higher than marked.<br> <br> I have in the past seen it immediately and brought it to the attention of the clerk and this seems an even worse option than just paying a few rands more. First they need to practically let a bomb explode next to them before getting the manager's attention to void and fix, causing a GIANT waste of my time and great annoyance from the client waiting in line behind me to check out. This is firstly embarrassing and time consuming as well! <br> <br> I estimate that I have been overcharged around 10 times in the past year that I have been shopping at this store and I find this ridiculous! <br> <br> The store is right across from home and thus the most convenient to shop at, but having regard to the constant overcharging I am seriously considering doing my shopping at P&P which is +-5km further to drive to....<br> <br> The overall service in the store is also at an unacceptably low standard and there is always too few tills operating. I also have an issue with there being short stock quite often.
