Posting seeds within Ireland !

I have come across an Irish website that sells seeds (I think they are based in either louth or dublin) anyways, I have not made an online purchase yet because I am worried about them been posted to me (I live in another county).
My worry is, will the gaurds know? will an post know what is been posted ?
Am I been too paronid?
Please can someone advice me or help me.
Cheers

you'll be fine seed banks use discreet packaging..order from uk also with no problems..good luck.
