PLEASE NOTE:  The prices shown on EDTM's website are FOB factory Toledo, Ohio USA. EDTM's website prices DO NOT include shipping, insurance, VAT, duties, customs and brokerage fees, or any other costs that are associated with importing the products to a given country. If you notify a distributor in your region, they will include all of these costs in their quoted price. Because of this, be aware that the distributors price may seem higher than what is listed on EDTM's website. In reality, the distributors' price will be better than EDTM's website price because the distributors are purchasing the products in volume, helping to amortize the cost of importing the products to your country.
