Pricing: Speaking of making it worth it, price everything so that it’s a deal, and make sure you put a price tag on everything, to avoid on the spot brain freeze or haggling. The general rule is 50-30-10 – new, unused items get priced at 50% of their retail cost, slightly used items = 30% of retail, and used items = 10% of retail. Also, if you’re selling books, CDs, or other small items, try a “Buy 1, Get 1!” or similar package deal. For customers, this feels like a great deal (so they buy more) AND all of that stuff you don’t want anymore goes away. By the end of our sale, I was ready to start giving books away to people just so I wouldn’t have to box them up or move them again, but because we did a package deal, almost all of them sold.
