We see Ruggie haggle with Jade in a vignette, Deuce and Kalim during New Year’s and Sam on a day when he has gone to the school store without Leona’s wallet.
His PE vignette consists almost entirely of his efforts to talk Sam into selling him a 7-mark drink for 3.5 marks (though he says he probably could’ve gotten Sam to go as low as three drinks for 7 marks), but in another vignette we see that Ruggie has the authority to charge school store expenses to Leona’s account, so he doesn’t always need Leona’s wallet.
Sebek has a Glorious Masquerade line of, “I saw Ruggie haggling at a festival booth. Really now, must he always do that, even in another country?”
When spelldrive club members talk about taking the bus into town Ruggie asks them to pick up 20 boxes of drink powder for the club, as it is 6 madol more expensive to buy it from the school store despite how it is not Ruggie’s money—it is the school’s—with Leona saying that their club is well funded.
Ruggie says, “I pretty much only use hand-me-downs and freebies,” and the shirt in his fifth birthday vignette is apparently one that he picked up from somewhere rather than bought.
In the vignette itself we see Ruggie getting empty snack packaging from a classmate to use the code for a gift card lottery and using soap that was left behind in the Savanaclaw washrooms by someone else.
Ruggie says that he usually just washes his face with water, but using soap sometimes can feel refreshing.
One thing that is not a hand-me-down that Ruggie uses seems to be a brand of oil for his skin, hair and ears, that he invests 300 madol (3 thaumarks) in because it is better to prevent problems in advance than end up in the hospital later.
