Aren't hostas eaten by deer? Son lives across from a large park with tons of deer and they are regularly in his unfenced yard. So that's another consideration. If deer don't bother them, I have several I could chunk off for him (I don't get deer even though I live on acreage and I know they are in our back woods).
I'm not a fan of big box stores in general, and always get my plants from local nurseries. I only very rarely do mail order. I like to check plants out in person and chat it up with someone who knows what they are talking about - all part of the enjoyable plant-buying process for me.
