The toy, which retails for about $50, is selling for between $100 and $250 on eBay. On Black Friday and Cyber Monday, a Hatchimals toy was sold every 30 seconds on the auction site, according to the company.
Several eBay users have put the toy up for $100,000, but don't actually expect people to pay that price. Instead, the high price tag is a tactic to lure eBay users to a seller's auction page. Once there, users click the "make offer" button and send in a lower-priced bid.
Brothers Mike and Stan Zappa, however, price their Hatchimals between $60 and $80, just over market value, and let demand set the price.
"We've seen the toy selling from $140 to $225 this past weekend for Black Friday," Mike Zappa told CNBC.
Zappa and his brother predicted the Hatchimal craze back in October and spent more than $5,000 on about 100 units of the toy, hoping to make a little money for the holidays. After selling 35 of the toys online, the pair have broken even on their investment.
Mike, a single father of two, will put the additional money toward a Disney cruise trip for his kids. Stan, who works 80 hours a week running a pest control company, has already purchased a new couch and will use the extra cash as a cushion around the holidays.
After making back their investment, the brothers opened a Facebook group with the goal of giving away a handful of Hatchimals toys. The group currently has almost 600 members.
A word of caution: Not all of these social media giveaways are legitimate. So make sure to carefully vet a seller before forking over your hard-earned cash or sharing any of your personal information.
