Good morning Malt...
Driftwood from local rivers and streams, ponds, lakes, etc. is great stuff. Completely safe with just a little rinsing or scrubbing. It's tons better than the expensive pieces at the LFS. The LFS stuff leaks tannins into the tank that can affect the tank lighting.
Never bought the natural pieces though. I've always gotten them locally, free. My tanks are full of the local driftwood and rocks.
I guess if the price is right, the pieces might be very nice. Hard to believe it could be shipped very cheaply, even ground would be costly, because the shipment would be to a residence. If you do buy, have the shipper ship to your business work place. Could save a little money.
Sounds like one of those "too good to be true" deals. Buyer beware!
