I just had the same problem, fortunately I did not buy much. I washed two quilts that were done except for the binding. Had to trim them up after that, but it worked, they smell much better. Now I just have to bind them.
There was bag with 600 squares cut 2.5 inches. Couldn't wash those so I quickly sewed them into 16 patches, then put them in a gallon size ziplock back with a fabric softener. That seems to be working pretty well at keeping the smell bearable.
