Black Friday and Cyber Monday will be the biggest shopping days of the year. Blockbuster deals will be all over the place and the best ones are on eBay. Shoppers need to double up as several products are selling out at breakneck speed.

eBay hosts a load of the hottest selling items. Hatchimals are among the breakthrough products currently making headlines. They have become one of the most sought after toys of 2016.

Hatchimals are animal toys covered in large plastic eggs. Interactive play is needed to get the eggs to hatch. In time, the eggs hatch and reveal the little creatures inside. Hatchimal prices start at US$100 (AU$136) on eBay, where one Hatchimal toy is sold every minute and a half.

A familiar toy species, meanwhile, is unsurprisingly taking over the buying bonanza. Pokémon products are red hot items that are selling out the fastest, with one Pokemon-related item sold every 11 seconds. Pokémon fans should get their fix before Black Friday and Cyber Monday arrive to avoid getting left out.

Hot Wheels collectible toy cars are also highly in demand this holiday shopping season. A lot of great Hot Wheels deals are available individually or in sets. A red Hot Wheels Custom ‘69 Volkswagen Squareback 1:64 art car currently goes for less than US$7 (AU$9.50), while a complete set of the ten Hot Wheels 2016 1:64 Garage Series is available for as low as US$25 (AU$34). One Hot Wheels toy is sold at eBay every 39 seconds.

The Nintendo Mini (NES Classic Edition) is another fast seller. The remake of the classic Nintendo Entertainment System has brought back a lot of good memories to fans of the original console. It has also drawn the interest of young gamers as well, as evidenced by its overwhelming demand.
