I don't do much as far as toys go.....we use tubes and boxes and stuff that's free.
For supplies I use www.bunnyrabbit.com because they're here in Texas and I can order stuff and pick it up at a show. I do like their service when I've had to have stuff shipped.
Funny you should ask. I am the webmaster of a pet supply store and I am here doing market research. What do you want in a bunny store? what products do you want to see and what categories would you want to find?
