Well either you have a really good priced LFS
or your looking at the shipping wrong.
Sure on some items the LFS
might be priced compeditivly after shipping if you order 1 item and have it shipped.
But the savings should come into play the second you order a second product in the same order. Most of the time additional items to the order dont drasticly affect shipping.
I usually dont order one item at a time unless Im desperate. I usually order up 4 items or more. Thats when the savings come into play.
