the plants shown are a mixture of demanding and non demanding stuff. unless you can keep the higher light - more neededy plants your wasting your money.
i would say about 30-40% of the plants you will get will die in the first week or two. due to transportation and your aquarium conditions (forgive me if you have a hi tech planted tank)
LTP are known for their good vallisneria though!
you would be better off getting plants from fellow forum members as these are often, larger, healthier, have a longer root structure and sometimes they will be mother plants which is even better.
