When I first discovered online pin trading/collecting, I didn’t want to spend $30+. But soon I realized I’d never get any pins otherwise (read: DSF /grails), so I bumped the limit to just under $40, including shipping/taxes/PayPal fees. So the most I’ve ever spent on a single pin is $39. I’ve probably cheated when shipping would’ve pushed it over my spending limit by just buying another pin. Then I justify it to myself by splitting the total cost in half - and that’s how much each pin cost, lol. So long as each individually is about $35 at most, then I’m good, haha. That’s also how I decide whether I buy a pin set or not. I was super close to spending about $65 on an eBay auction for a grail, but luckily someone outbid me.
