Thousands of South African fans queued overnight at supermarkets and shopping malls on Thursday for a chance to buy 500,000 unsold World Cup tickets.
There is still availability for all fixtures, including the final at Soccer City in Johannesburg on 11 July.
A 64-year-old man died from an apparent seizure as he waited in a queue in central Cape Town.
The tragedy in Cape Town came after fans from all over the country had queued from Wednesday afternoon as South Africans rushed to get World Cup tickets.
BBC Africa correspondent Andrew Harding says there were exuberant scenes in Sandton, north of Johannesburg, where people camped out on the street through the night.
“The last time I waited in a line like this was when I voted for Mandela,” said one man in Soweto who did not want to give his name because he was skipping work to stand in line.
BBC Sport’s News Correspondent Gordon Farquhar said that there has been a problem with the main server to FIFA’s ticketing database, resulting in long waiting times for queuing fans.
Many South Africans had complained the original process, by which tickets were sold through Fifa’s website or in a complicated ballot at a local bank branch, excluded people without web access, credit cards or the disposable income to pay for their tickets months in advance.
“We are excited about these new initiatives, which make the process much easier for everyone,” commented World Cup 2010 boss Danny Jordaan.
“We have always said that it is important that we make this World Cup more accessible to the people and with over the counter sales, we believe this measure is consistent with the needs of the fans.”
Ticket prices are also well above normal for top-level football in South Africa.
A special category for local residents sells at 145 rand (£13) but costs escalate drastically in higher categories for better seats and after the first-round group phase with prices for premier seats at the final coming in at 6582 rand (£581).
Demand in South Africa had initially been sluggish but the most recent phase saw 85% of the 240,000 tickets sold between February and the beginning of April go to locals.
Fifa has since revealed that 2.2m tickets have been sold for the tournament, which kicks off on 11 June.
