It’s important to remember is not to overprice your items for sale. It’s nice to make money, but clearing out that excess clutter should be the ultimate goal. A good rule of thumb is to sell things for one-half to one-third their original price. Your kid might be very attached to that old stuffed animal, but even though it’s super cute, it’s still a secondhand product to a new owner.
Also, try to price things with round numbers–25 cents instead of 15, $2 instead of $1.80. This way, you’ll avoid juggling loose change and making math errors when calculating totals.
