I got free shipping, I forgo to mention. It has cheap (less than 10$ shipping) or free on a lot of items. Search around their store bc some items they label differently though they are the same (ex: java moss plant- with shipping vs java moss for shrimp- free shipping)
I read somewhere that the reason they send it so cheap is because they cut corners around the importation laws or something but thus far, the only problem they seem to have is taking a long time to ship. I think for this reason, you should order java moss and marimo moss and other hard-to-kill plants. Then get your more fragile plants locally.
Go to stores and ask for cuttings from their salvinia (some stores see it as a pest plant and don't sell it normally) or search online from kijiji. I got mine from a girl on reddit locally, she gave them all 100% free. Just make ads letting people know you want their plants.
