oh dear i feel a word of advice coming on already
stick to your menu and pricing--which i commend you for in the first place
peeps will want to get it thier way -- shoots a big one in the whole sanity thing huh
they can get it their way at burger king
'i only need 16 cupcakes--can't you break a dozen for me if i already buy one dozen???? pleeeease???'
'i can sell 12 or 24 or how about 36 and you can freeze the rest ;)"
srsly--try to keep it as well organized as you have it written out--
you cannot please everyone and don't let them bait you or play you
bravo for a great summer project
and man it's not even april yet--how terribly type a you are--in a good way i'm sure ;)
