When Ray gives you a quote ... he often then gives you an invoice with all the items you requested (in your quote) in it ... including the shipping costs ... he then lists this "item" as having free shipping, but the shipping (which is almost always reduced from what the website would give you) is part of that quote ... so it becomes a bundled item just for you.
It seems that once you reach a certain level ... the shipping costs max out ... usually around 110-150 or so. So obviously the bigger your order, the smaller the overall shipping cost % will become.
What I do with some of the local folks here ... is we order stuff together and that allows us to all share in the shipping costs ... and another excuse to visit each other.
