Retro Vegemite sanga prices shock

A canteen price list for a South Australian primary school from 1977 has people in disbelief over how different the pricing and food used to be.

A photo of the Seaton Park Primary School canteen menu was shared to Reddit yesterday, sparking a lot of conversation online.

The first thing people noticed was how ridiculously cheap everything used to be.

A vegemite sandwich was just 17 cents, a chiko roll cost 25 cents and a good old fashioned meat pie would set you back just 25 cents.

However, some users weren't impressed to find sauce would cost an extra 2 cents.

"Charging for sauce since 1977," one person said.

"2c extra for sauce! Oh the outrage!" another said.

Those with a sweet tooth could pick up a cream bun for just 19 cents or a bush biscuit for only 6 cents.

On those hot summer days a frozen Sunny Boy would set you back just 6 cents.

"Wow that's crazy. I remember 10c sunny boys," another person wrote.

One added: "No wonder my parents think my daily coffee is expensive.

I was in primary school in 1977."

There were some other weird notes on the menu that people noticed, such as younger children not being allowed some drinks and soup.

"Years 1 and 2 are not allowed bottle drinks or soup," the menu read.

One user shared the school's current canteen menu and the available options are very different.

Kids now have a choice between burgers, salads, pastas and wraps.

There are also significantly less junk food options available.

A pie now costs $3.70 and extra sauce is now 40 cents.

Hot dogs have gone up from 25 cents to $3.60 and a small salad is now $4.50, compared to the 31 cents it used to be.
