yesterday i have receive 100% deposit from UK customer , he pay money by western union . we have contact almost more than  2 months time . i receive his enquiry on 2th of June . 

this customer want to buy barbed wire and sheep wire mesh from me . but his aim price is very very lower . barbed wire aim price is 6 GBP/roll , sheep wire aim price is 10 GBP/roll . barbed size is 200m/roll ,wire diameter is 2.80mm .

sheep wire mesh size is 1m*100m/roll , both material is electro-galvanized , lower carbon steel . 

barbed wire weight is 27kg/roll , EX-W price is 8.0GBP/roll , no add any profit . but customer aim price is 6GBP/roll .

it is big gap than factory quote . i have agree with customer aim price , because i don't have too many customer in my hand . so i decide to meet customer demand . unless it cause loss for myself .

i am worry about that customer are satisfied with sample order , he can sell very well too . but next time he still keep raw aim price , how to do it ? 

because i have loss , it is impossible to loss again and again or next time ? who pay me this time loss ? i am confuse .

i and my wife both poor , but we have enough confidence to  overcome kinds of question in my wife . if customer can't buy next time , we have cause loss . so i am very sad . 

what is your idear ? return back money to customer or finish this loss order ? pls let me know .
