For some reason, this only works on the 4-pack boxes of the Oatmega bars and not the 12-pack. Anyways, the pricing is $5.99 per 4-pack and then $3.59 for the next 4-pack for a total of $9.58 for 8 bars. You can pick up in-store to save on shipping or order over $25 for free shipping. I ended up ordering 24 bars for a total of $28.74 (saving $7.20) with free shipping.
