Please note that buy.at product feeds in gzip format are corrupt. There is no CRC32 or ISIZE value in the trailer of the file which is required. Please see the gzip spec. You can see this by opening a valid gzip file and their invalid gzip file in WinRAR or 7-Zip… there’s no input file size or CRC in the file.
