Basically, they are complementary and are not any extra cost. You can use a BIN with a Best Offer to let people bid on your BIN items. Say you have a card you want to list with a $2,000 BIN but you'd gladly take $1,800 and if push came to shove you'd take $1,500. You do a BIN at $2,000. Ebay lets you set a range of Best Offers, one to take automatically and one below which you automatically reject the offer. You set the automatic accept at $1,800 and the "go away" floor at $1,500. If an offer comes in between the 2 you have 48 hours to review and decide whether to accept it. If an offer comes in above $1,800, it is accepted automatically and the auction closes. If one comes in below $1,500 it is rejected automatically.

I've been very happy with the results using this set up. One trick: set the floor and ceiling Best Offers at odd numbers, like $1,798 or$1,499 rather than whole numbers. Seems to help.

If Ebay did a better job of publicizing it I think we'd see more action on the BINs. It does take a bit of thinking, which I realize is difficult for many Ebayers.
