Misleading "price sticker"

I bought a lamb pack from Woolworths - Bluff today (25.05.2019) firstly, the only reason I bought it was because the pack had an additional label/sticker that looked like a reduction in price. The price was R300.08 but the additional sticker said R119.00. I get to the till only to hear that I've been lead to believe elsewise and the price is actually R300.08. So I pay for the meat and proceed, upon packing my freezer I noticed that the expiry date is the 27th, so WOOLWORTHS - do you expect me to consume a R300 pack of meat in 2 days?? I'm so confused. Also, the sell by date and expiry date is exactly the same??? Please explain. I feel absolutely ******.
