Bookcase arrived today as scheduled. Some staples holding the back on had pulled loose in shipment; I replaced with small tacks. We are short 4 shelf support pins; will pick them up from a local hardware. Had difficulty inserting pins in several of the holes; used a drill bit to clean out so the pin would fit. Was not sure how the shelf retainers were fastened to the sidewall of the bookcase for shipment; finally gambled that they must be tacked in place (suggest you flag these so customers will know how to remove).
