Here's the breakdown. They advertised a burger for R10.00, which normally sells for about 25. It was promoted all over, from TV to facebook and twitter. The special lasted for one day only. Here's the problem though, they had so many customers in their branches all over SA, that they actually ran out of stock.

Naturally this got people upset and they have been ranting on a few areas online and business gurus are now calling it a marketing blunder as they used social media to spread the word, and because these mediums are so popular, they could not deal with the amount of people that responded to the special.
What really gets me, is that I think its not a marketing blunder at all, it was actually a brilliant tactic. Look at the response they got for the promotion. In all honesty, to me, it seems like it was a business blunder because somehow they didn't realize that advertising food at that price was going to give them the response they got and they were unprepared.
I guess I am just a tad upset that its being pinned on marketing, and not letting the chips fall where they are meant to, and that's business management itself. What do you guys think though, was it a marketing blunder? Would you promote something like that and not prepare yourself for the influx on the day?
