I'm not getting a good result with that link. You may want to edit it! Is this your wishlist: http://amazon.com/registry/wishlist/Y3UABVISESRZ
Also, you need to make sure there is a shipping address associated with the list or else nothing can be sent to you! The AutoModerator comment on your post contains a link that will show you how to do that. :)
A lot of non-Prime items can be costlier, and a lot of items only come in bulk, that's true. But there are many staples that are not too terrible. Sometimes it just takes a little looking around. For example, you have this Skippy PB on your list. That's 28 oz for $13.65 ($0.49/oz). But there is also this Peter Pan PB which is $15.05 ($0.13/oz) or this Add-On Jif PB that is $9.46 ($0.12/oz)
