I know, I know...never underprice, but my daughter's school does an open house that is like a farmer's market. We make breads and butters and stuff from the garden that the kids have tended to all year. The herb bread baked in clay pots generally goes for about $6-10.
This year I am making Lavender Cupcakes (they were a hit last year) and packaging them in individual cupcake boxes...also in a box of 4. I am also doing Rosemary Shortbread Cookies and packaging them singly and by the half dozen. They are approx 2-3 inch cookies.
So I need bake sale pricing, also keeping in mind that the event is Friday, and Mother's Day is Sunday, so people will be looking for gifts. I am going to package it all up right purty, to help with that!
Also bears mentioning that this is NOT business related...no one will know where it is coming from, so no need to worry about setting a precedent.
It's a bake sale which means people expect cheap. Don't price it like you would for a "regular order." I would say at least 1/2 of what you would normally price it for.
