I have only ever bought from ckproducts but need some other options, not sure ck is a great discount?

What other wholesale companies do you buy from?

Also, where did you buy your edible printers from? Looking for those too.

I don't know what specific products/supplies you are looking for, but have you seen this thread?

Hopefully, the suppliers on the list will be helpful for exactly what you are searching for.
