But on one level the whole point of a pledge drive is:
Is "X package worth it to me to give Y money to Person/Group Z" (remembering that some people will peldge an amount and expect nothing in return). If so, then it really doesn't matter if there are better options one could make. But if what someone wants is to make the best deal possible, take the steps to get it.
Even if one ignores the peculiarites of USPS shipping costs (which have been discussed to death here and elesewhere), the thing is Rich can't change the amount a pledge point costs even if he wanted to once someone has chosen it.
