* [No GBP] Fixes double esword discounts (#73847)
## About The Pull Request
In a recent PR, I have inverted the sales values to make it easier to
calculate and modify the discounts. I did not notice that double eswords
overrode this function, thus, deswords got terrifying discounts. This PR
fixes that. Sorry about that.
I am not happy about the current solution (adding an assoc list directly
to the uplink_item datum has not worked for some reason, it initialized
as an odd value), but I will soon refactor discounts anyways.
## Why It's Good For The Game
There is a good reason double eswords have smaller discounts.
## Changelog

fix: the double esword sales are now smaller than regular sales
