There should be a way to search for multiple items at the same time and show
which store has the majority of what you are looking for. Almost like a shopping
list. Instead of putting in an item and then going through a store looking for
other items needed, it would show many options (i.e. the cheapest store with
the most items or just the store that has the most of what you need). Is there
a way for bricklink to engineer something like this?
