Went to my local BB in search of the Insignia 48 pack batteries and found these instead.

SKU: 5467125 – Panasonic – eneloop AA to C Rechargeable Battery Spacers (2-pack) – White
SKU: 5467107 – Panasonic – eneloop AA to D Rechargeable Battery Spacers (2-pack) – White
Each pack rang up $4.99 and I have posted pics of the in store tag and pictures of the batteries.
YMMV since BB online shows that they are $9.99 each. In store only.
