Once Upon A Child Green Bay is a buy-and-sell children's store. For shoppers, it is great for parents on a budget, with very fair pricing and racks full of quality clothes for a great price. Specific low prices are noted, such as size 6 shoes for $4, snowpants for $6.50, and a winter jacket for $10. However, some prices can be higher, like snowsuits for a flat $30 or size 10-18 clothes priced similarly to Walmart, and occasionally an item may be priced above its original store tag. For sellers, experiences vary. Many report a great, friendly experience where staff explain policies well, offer more money than other local resell shops, take a ton of items, and complete the buy very quickly, leading to high recommendations. The store is described as very clean and organized, with workers noted as way nicer than at another location. In contrast, one seller reported a poor experience with a staff member being rude and snarky during their first time selling, which felt unwelcoming. Overall, many customers love the place, will continue to come back, and recommend it for both shopping and selling.
