Accordance just announced a sale on the Word Biblical Commentary series. The 58-volume set can be purchased for the Accordance platform for 50% off, which is a little under $300. This is a great sale and a good time to purchase if you are looking to augment your library. I normally do not recommend buying an entire series because they can often be of uneven quality, but the WBC is highly regarded across the board. You begin to break even, so to speak, even if you only want about 10 or so of the volumes. If you plan to use more of them, this becomes an even better deal. Highly recommended if you are on Accordance and need commentaries for preaching, teaching, or study.
