This is a really great question and I know alot of people are wondering the same thing.
My advise is to not look at it like, " I need a standing order item worth 1500 VP."
Instead think about what you use around the house on a routine basis and put those items on a standing order. Otherwise there are other great items to put on standing order such as - S Builder Co-op, PSA's to Go, Silver, Advanced Liquid Nutrition and many others.
