I did have this wonderfully detailed review(it was a work of art) but then Firefox crashed. So quick and to the point. Advertised price they should of payed for my gold $450.00. They offered $300.00. Took items to another place offering a couple dollars less per DWT offered exactly what they were advertising $400.00. My mass and caret calculations exactly matched theirs. Just make sure you test check mass and estimate what they advertise they pay before you commit.
