Have a tight budget this year.

I am looking for ideas on saving money for a backyard show. I will prolly use AWF because I have the best discount with them. I'm assuming the best way would be to build a show from a mix of 200 and 500 cakes and use very little canister shells.( Maybe do a finale only with can s)

Any tips would be greatly appreciated and what called are good for the money.

Thank you in advance.
