Is that what you want the plants for? Are there any plants in the area you got the shrimp from. You could try to take a few if there are any and see how they fair in your tank.
If you don't want to buy from ebay, all I'd every say is only buy from people who have a defined list of plants that your pack will be made from. And not 'there may be plants from this list, but the list varies due to season' etc etc.
You're better to pay a couple ££ more to get to pick specific plants from a list. Or know that the plants they pick for you are from a specific list so will definitely be aquatics and suitable for your tank.
