country kitchen is a very good for filling - the best prices I have seen. the other stuff is pretty good.
sugarcraft is good, they have good prices on some stuff.
oassis is good for the foil on cake board
If you want you can e-mail at this address: leana@rdmfg. net my home computer is down and I can send a list that I have put together over the three years on supplies. and who is better to buy.
lets say I need filling from country kitchen and need some other things I really search differant sites to see who is the best including shipping. I have one place that their cakes boxes are good prices and pans are pretty good. they are expensive on their filling, except for cream cheese (they are the cheapest on this one), so I need cream cheese I will order from them and then and boxes or pans (prices are pretty good for pans)
I hope this helps you.
