Build-A-Bear employees said Thursday evening that they weren't sure that they had enough inventory to accommodate those still in line, but that more supplies would be available Friday.
Lines were still long at Build-A-Bear issued a statement Thursday about the "overwhelming response" to the promotion, stating there were safety concerns in some locations, and that some customers were turned away.
"We feel it is important to share that, based on the information available to us before the day began, we could not have predicted this reaction to our Pay Your Age Day event," the statement reads.
"In response, we distributed vouchers to guests, who were present in lines, to be redeemed for a future purchase," the statement reads. The company says they will honor the vouchers through Aug. 31, 2018.
