Sorry for not posting that link last night, but O how accounting and business law have been taking their toll.
Anywho! I found the link...it didn't help that my "favorites" on this computer is...forever long...lol, and i got a few other links you might be interested in

-heres a link that lists some suppliers in the US...none in Canada though, should be able to get a good deal on accounta our dollar being worth more now and all (last time i checked atleast)

Also... this is from personal experience, everytime i go the the petstore and they have those home-made dog treats...i always get hungry and want a chocolate bar lol...so might think about having those ahahah I have yet to find a pet shop that carries them...but i know i'd buy them every time i went in lol, might just be cause i'm a chocolate addict though, but think about it...a kid comes in to buy a betta (which is probably the ONLY fish you should sell a kid..well a young one atleast) ands going outta the store...I want that mommy! Mom...thats a dog treat hun....well get something for ya at the drug store, kid, but i want it NOW! mom:...(if you had chocolate bars...tehres your sale!) lol I rest my case
Question for ya, do you have an idea of were your gonna set up shop yet? or still to early in the plannng phase?
