I've been pricing standard 3 tier cakes to serve around 85-100 guests. Even publix wants around $330. I found a lady just starting up her cake making business and thought she'd give me a great deal but her quote was $356. Is this a good price? We're paying for the wedding ourselves and I'd rather not spend a lot on the cake but I don't want just a sheet cake. Am I being unreasonable in being disappointed by these prices?
