doesn’t matter. The price is outdated and needs an update

Not sure you understand. The chulo is 8 months outdated, and so it needs a mini to show what it's currently worth - which means finding sales for that chulo, within the past 2 months (if very few sales, take the last 3 months).

So there are two sales for the chulo, which you could use.

Just checked, there seems to be a few other sales, than just yours, on the pullover. You may want to check them out.
