They gave me a quotation that was very favorable then after I paid and got a sample they all of a sudden told me that they mistakenly gave me quotation in mm not inches so the price for more is 10x what I was told and I specifically told them it was inches several times, they are just trying to steel your sample money, stay away from this company.
