I'm bidding on some Teaching Company titles over at ebay and so emailed my friend Tammy (the queen of ebay) for some tips:
-- don’t bid on something where the rating is less than 98%;
-- if it is lower than 100%, read the negative feedback;
-- if you can, bid at the last minute (literally – set a timer and bid when there is less than one minute left);
-- as far as Teaching Company items, you might want to check with Michele, Lorri, me (so we are not bidding against each other – hahahaha).
