All their anubias are less than $10, I think you were referring to the fern...they claim it is rare and hard to get so that is why it is more pricey...I don't know their prices seem in line with the other online sellers I have seen.
All their stem plants are in the dollare range. The standard java fern is $3, the thin-leaf java fern is the only "expensive" plant they sell. The Vals are $.75. I don't know how much cheaper they can get. It just seemed like this seller was unfairly targeted for having "high prices" which they don't IMO and that is why I am defending them.
I don't really buy from online sellers anymore though, just aquabid and private trades.
