Well I can't guarentee anything other than they seem to have the best prices I have found,and was or still do offer free shipping.
If I read their add right when you order tracks they are not sold as a set,but individual tracks at $20.00 dollars per track for the metal ones.So a set of metal tracks is $40.00 dollars which is still the best price I have yet to see.Hope everything goes well for you on your order,I have allways had good luck with them.
