As a seller, I find that I'm less willing to work on price when these coupons are active. That said, I do understand the buyer psychology. When I submit a 'BIN/BO' price, there's no way to cancel it, so I don't want to stick a high BIN/BO price out there in case the seller doesn't respond until the coupon is expired. I tend to try to find auctions that close in the time frame, or look specifically at BIN items without worrying about best offer. It's a bit of a game, but stuff like this is part of what makes the hobby fun to me.
In any case, bounce, I have added you to my favorite sellers list. Your stuff is reasonably priced and I'll be sure to check out your store first next time a coupon comes up.
edit: I also feel bad sometimes because some people clearly don't know about the coupon. I drove hard (didn't reduce price) on a Koufax RC last night because I assumed the buyer would wait to pay until today and get a huge discount. I got almost what I had initially hoped, so I felt pretty pleased with the sale and the assumption that we both walked away with a good deal. Nope...poor guy paid immediately after accepting my counteroffer. Had he waited just a few hours, he could have gotten the card for quite a bit cheaper.
