I have a family member ordering some cookies for her son's (my cousin's) rehearsal dinner. She's ordering plenty in advance and I have no problem making the cookies, but I have no idea how much to charge! Is it wrong to charge full price ~ she wants pretty time consuming cookies ~ or should I give a discount?
I have no idea what to do!!

Hmm, i would assume that if she is requesting time consuming cookies, she'd insist on paying full price.
Then, as a family member, you could maybe add onto the order with an additional amount of those cookies, or make some different ones to add in. That's just MHO

What I've done is give them a good discount... they will appreciate it, and know that your business is serious... unless you want to give it as part of their wedding gift

Thanks for your suggestions ~ much appreciated!
