Price inflation

I bought a Salton 20 liter urn last week, the original price was just over R2000. So when I saw a 56% off, I jumped at the offer and bought it for R1300. Today I see the same urn and it's price is R1699 and has a discount of 17% which then makes it R1395.

I am very upset because it means they inflated their prices. They are falsely claiming things are on special when they are not.
