I agree with iluvstarz. You definitely should have a policy or price list in place. I'm new to selling bows but have found people can catch you off guard when they ask for a discount or if they buy x-amount, what kind of deal can they get. You don't want to regret telling them a price only to find out you are giving the item away for almost free (remember your time, supplies, etc)
I recently made a cheer bow (fairly basic) for a coworker and she then asked for an additional 16. I told her I would be willing to give her a discount but the additional bows would be at $6 each.
Your customer is lucky to get your cute cheer bow for $4.
