7 Kids College Fund will be selling High Hopes stamps. They are great to deal with. I always receive my order in a few days from them. You can email her with any specific stamps you would like if they are not listed.
I am wondering how long it is going to take them to get their wholesale orders out though!
So glad that Chrissy is illustrating for some more reliable companies now. Check out her blog:

You can even get them digitally from Squigglefly.
