I have only ordered live aquarium plants through them and I was worried how the shipment would work for live plants but I must say that they had done really good packaging, like they put the effort and consideration into it. Only one of the plant (Ceratophyllum demersum) was kinda messed up and turned into green goo upon delivery. The pricing was okay but the plants are bit smaller than they make them look on their site, I was even very confused seeing the size of the parcel itself being so small.

Really a nice website. One of the best major online retailer of Aquatic plants.
Very affordable and reliable. Although they do sell aquarium livestock, I haven't experienced it as I live quite far.
While they do lack some species of plants such as bucephalandra,they have quite a large selection of epiphytes, and stem plants in potted,wabi kusa and bare stem variants ,and very few varieties of Tissue Culture plants.
