A buyer has emerged for the bankrupt Buy Buy Baby chain, but the retailer’s physical stores are still going bye-bye. Dream on Me, a New Jersey-based manufacturer of baby gear, has agreed to pay $15.5 million for Buy Buy Baby’s trademark and accompanying digital assets. This deal is similar to the one struck last month for sister chain Bed Bath & Beyond, whose digital assets are being sold to Overstock for $21.5 million. Meanwhile, there are bargains to be had on Rockville Pike as both stores continue to hold going-out-of-business sales.
