buyers usually ask us to post the catalog for their reference.due to small amount,we can not ask the buyer to afford shipping cost,it is also a big afford for us to take at all.this is why we sometimes refuse to post the catalog to some buyers that they have no more interest to buy.if the buyer has the account of DHL or FEDEX,that is fine.we do not tend to post the catalog because we can not know if you really want to buy our press brake .actually,we always hope to check the idea of buyer through this way.if they really want to buy our machine,they must hope to pay this express cost.after all,this is not domestic express,the cost is from USD 20 to USD 50.it looks like that this is not big money,but if you spend hundreds of express each year,it would be a big money.
