Do you ever give certain vendors a tip for appreciation on orders? Either by a tip listing (usually like $5 - $7) or choosing a more expensive shipping option so they could keep the change, something to that effect?
I usually tip 2 specific vendors I use on occasion for higher priced items. One has a tip listing, the other I just double up on shipping so they could keep $7 from it for themselves. Both generally due to just an overall amazing experience, customer service down to product.
no... they are already making a profit
