When people provide services or items at a discount, (Including myself to others), I always have the full price listed and then extend a discount either to each item or the total in whole. That way, people can see the retail value (not inflated values mind you) as well as the discount that was given.
As long as you don't wouldn't pay more for the equivalent service or products, and document it properly, I think you are terra firma.
I wouldn't see anything wrong with the situation you described. As long as there are receipts to back stuff up with, I would go with it. If you were paying her more than the stuff was worth, then you may have some issues to deal with. But I will assume you aren't and therefore, I would have a hard time finding issue with it.
An itemized receipt that includes contents and a copy of the catalog with the retail prices clearly displayed will cover you. It is not a conflict of interest to purchase the items at a discount, regardless of where or who you purchased from. It can only be seen as a conflict if it is interpreted that you only bought the gift baskets because she sold Avon. Usually we accept these items as donations and do not purchase them.
The company information. Name of the salesperson. The specific item(s) description, the normal price, the discounted price. The date paid and check # and what the item was for.
The irony of commitment is that it’s deeply liberating-in work, in play, in love. The act frees you from the tyranny of your internal critic, from the fear that likes to dress itself up and parade around as rational hesitation. To commit is to remove your head as the barrier to your life. --Anne Morris
