Hopefully this is the right place for this
http://www.mainelyratrescue.org/rattieblog2/This is a fantastic small animal rescue that rescues/rehomes mostly rats, but occasionally mice and other small animals, too. They have 2 stores (click MRR Stores on the left) - one for food/bedding and the other for hammocks, toys, bowls, etc. All proceeds go back into the rescue to help them help more rats/small animals!
If you use Harlan Teklad food, you can buy 5lb for $5 plus shipping, or 33lb for $25 plus shipping. They have the high protein for babies/mothers, and also the 14%, 16% and 18% varieties.
Also, this is actually one of the only places I have ever seen custom-made mouse-sized hammocks! I ordered three recently, and I'm eagerly awaiting for them in the mail! As soon as I do, I'll let you know how they are
