I would like to re-order A. However as the competitors are selling at lower prices, I cannot order at the same price I purchased previously. I will order 200 this time, so could you kindly give me a discount to $20 per piece?
I would like to place an order of A again. The group buying price is a lot cheaper, so I cannot buy it at the price I bought the last time. I will order 200 pieces this time, so can you sell them to me at $20.00 per piece?
I would like to purchase A again; however, I cannot place my order at the previous price since the bidding price is lower. I'd like to purchase 200 pieces this time. Could you please sell them to me for $20/piece?
