TODO
- probalby will error when asking for prices of completes when none there, look at full use of the function and make sure it does not chrash but prints error.
- make some kind of updatelistener that updates the site view when new prices or completeds are made.
- make completeds have the already existing price element as price instead of new one. maybe, look at it
- dates in lists are not in order, make it be.
