January? February? Valentine’s Day? Most retailers just want to make it through this year’s holiday shopping season before thinking about 2014. Besides, January is typically not a strong month for retail jewelry sales. Yet many shoppers have cash-in-hand to spend from work bonuses and family gifts. So it’s a good time to contemplate running a January clearance or customer appreciation sale to move some of your older inventory that did not sell over the holidays and to attract new customers into your store.
