jess, if you live in uk or europe i cannot recommend this seller on ebay more - last trading post.
he is one of the nicest guys you could deal with, his plants are 100% aquatic, healthy ect and you can even customise your order a bit! if theres something special you want mike goes out of his way to sort it for you!! he does a great starter plant pack (25 plant+) for about £3,99? they are fabulous. i got two lots and they fill the back of my 6 foot tank!
hopefully this link will work
