pixel

hi i’ve recently started to play again after a veeery long time so im just discovering the pixel/drip thing i don’t really understand how do ppl afford so many of those items ? like i’ve seen people giving away 20+ skirts so like 1.5M sc ? how is that possible is everyone paying hundreds of dollars worth of sc ? is there a way to get them cheap (except with the half off thing) ? also i’m playing on french server and lots of people are willing to trade a vip ticket for 5 skirt which i don’t understand 1 week here is 5,99 how is that worth it for them ? i have one and i don’t really understand if it’s a scam or not
