Heads up, deal hunters! Capital One Shopping is running a flash sale offering 12% cash back on eBay purchases. If you've been eyeing something on eBay, now might be the time to snag it! While 12% is a decent chunk of change back in your pocket, it's worth noting that this deal isn't quite as amazing as yesterday's 25% back at Walmart (if you saw that one!). Still, if eBay is your go-to, this is a solid opportunity to save. Keep your eyes peeled, because we're hoping to see even bigger and better cashback deals popping up for Cyber Monday! Don't forget to activate the Capital One Shopping extension in your browser to make sure you are able to take advantage of this deal.
