I find it kind of humorous that people (not only on these forums) seem to think there really is such a thing as "free shipping"! Especially on the B&S forums, some seem to think the seller just takes their stuff down to UPS, FedEx, USPS, etc. and requests the "free shipping service" from them.
There is no such thing as "free shipping" ... shipping charges are built into the profit margin for stores, or come out of somebodies pocket. If you purchase an item with "free shipping", then decide you don't want it and send it back, somebody has to pay those shipping charges invoked in getting it to you. They weren't "free", so you have to pay them.
I like the example of the free TT Backpack with lens purchase. Can't you just order the lens, return it, and keep the backpack? What if you want 3 backpacks?
