Sit ‘N’ Spin
Average original Price: $12.99
Potential earnings: $90
Parents loved these toys for their ability to entertain the children and tire them out. Toddlers could sit and spin them for hours while the parents rested. Now, the Sit’ N’ Spin is worth $90 on eBay, and it’s a great toy to invest in, as it will keep the child occupied while the parents are free to do other tasks around the house or take a power nap. At the same time, it’s a great way to tire out the child and get them to go to bed earlier, which means more time to relax for parents.
