Overcharged EGGS

I had gone to buy my weekly groceries during lockdown at Sinoville Woolworths, and came home, looked at my slip and saw that I paid R94.99 for 18 Free Range Large eggs. I was shocked and called the store to make sure they had the correct price. The lady's response was, that it was more expensive because it's free range eggs. This morning I went online to check the price, and for the exact same product it is listed for R69.99. I am very shocked, and I love buying from woolies, but now I am not so sure anymore. I will be contacting the store again and have them explain this to me.
