Hardware R Us

The local store.

What's on sale
Amongst other things, they have on sale the following items:

Renovation
You can pay them to renovate either the Cassie's Safehouse, or the Milk Farm's back room. Both would cost you 10,000, and take several days (the rooms would be unavailable during that time).

Note what you can't renovate the Cassie's safehouse until you finish the Cassie's rescue quest, due to her distrusting the outsiders, and renovation requiring to reveal this place to other people she doesn't know yet.

Trivia

 * One of the customers mentions a rumour about the store's owner having strange dealings with slumlords. This is likely a reference to Lust Doll Classic: in that game, renovation of the Safehouse's basement was a reward from the Don after completing the first part of Cassie's route.
