My opinion: fictional.
Sometimes, they republish the items/bundles, for the same price as the first time (without forgetting their fictional discount), or for a higher price (still fictionally discounted).
Sometimes, they inovate, creating a new bundle out of items from different bundles, with a new price and its new fictional discount.
Contrary to what people said, I do not think the bundles’ prices and their “discounts” are based on what the price would be if you were to buy the items on their own, but I could be wrong too. It feels to me that they are adjusting the prices on the go. If it sells, then it becomes more expensive, and the discounts are irrelevant.
Why do I think so?
Because July 2022:
Then November 2023:

From what I can tell, it is very tricky.
Some other items are sold in a way it could confirm the bundle discount theory though.
Example:
I bought the market stall. It is, just the stall on its own. 760cc.

Then, I had to buy the veggies. 700cc (deduction made from what I own of the bundle, or people say so).
Since 760+700 = 1460, we could give the benefit of the doubt to the theory that the 700 is a discounted price due to being part of the bundle.
1760-1460 = 300cc sale on the veggies.
So the actual worth of the veggies, sold on their own, would be 1000cc, with that theory.
We swim in shady waters with this Bazaar. In the end, only buy considering the price it is sold to you the moment you buy it, thinking only of if you are ready to buy it for that price, that’s all.
