Well it was worth a shot. I thought that maybe, just maybe things would go dormant in the pricing columns so I could reference the old markup values before correcting them and reactivating things for sale. But ignoring the the whole issue about doing this manually or with the cvs files, am I correct that the pricing changes were being implemented practically at the same time as the announcement? Not on Monday but today? This means there was no adequate warning to download the appropriate files to archive the old markup values in a reference document. I guess its my fault for not archiving these files myself every week or after every editing change on the off chance that Shapeways could change things at a moment's notice, and somehow also set new prices in the thousands of dollars for some porcelain models, meaning my markup values were set to zero.
