We would like your support to order this item at 500 pcs/lot and 2,000 pcs/year due to some main component parts we got requests from raw material suppliers need to order at MOQ 2,000 pcs per lot to covering their production cost. To not effected with you too much I would like your support to order at 500 pcs/lot and the rest 1,500 pcs take order in advance for covering 1 year the reason is we have to buy component parts at MOQ 2,000 pcs as per raw material suppliers requested and keep some in our stock although it is our cost which quite high but this is the best solution to support our business relationship instead of transfer to you whole 2,000 pcs.
