怎么那么巧？又遇骗子吗？

各位福友好！小弟9月7号时到了一封来自尼日尼亚的询盘，邮件发送地是在德国。和平时一样，我都是循例地回复一下。第二天就到了此客人的还盘。内容如下： this is to acknowledge our receipt of your offer on outdoor umbrella. presently am in hamburg germany to open our fisrt office in europe. we specialized in buying outdoor umbrella for restaurant, bar and garden for several years and it may interest you to know that last year became one of our most successful in business years on the trade. we he more than twelve wholesale outlets that depends on us for sourcing of good quality products. for this, we are pleased, proud and grateful in this business and would want to establish a mutual business relationship with your firm. meanwhile, i am waiting for our office in nigeria to send me feed back on how to place our first order with you, i will surely send your details of the quantity we are able to order. yours faithfully, mr. ugorji okorie 好了，看了看邮件，他的意思好像是一定会下单给我的。所以，待心情平复过后，循例继续回复客人。时间好快就到了9月9号。此时邮件又来了。以re: proforma invoice为主题。内容如下： we are placing order for the followings: description/ quantity: 1. model no. u-005（s80） open size 286×286×212cm qty: 1200pcs 2. model no. u-005（s70） open size 253×253×187cm qty: 1300pcs loading in 2x20ft container destination: apapa sea port lagos nigeria confirm us your most competative price for the above quantity based on fob and send us an official proforma invoice which we should present to our bank to enable them secure foreign exchange in your for. please indicate your bank detail on the proforma invoice and when goods shall be ready for shipment after your receipt of our 50% upfront deposit by t/t and balance of 50% against the bill of loading. we are looking forward to hing a mutual business relationship with you. 继续抑制激动的心情。 （越来越像是骗子了）。好，为了保持专业的态度，也不得不拟写一份pi。以防漏洞，所以把付款方式改为我司的30%前tt，出货前70%tt（邮件上也标明的）。到了10号的时候，客人来邮件。 please resend the proforma invoice and address it to our company as following: eagles & angels industrial ltd 256 adeyemo akapo omole estates phase 1 ikeja lagos tel: 234 8067117637 fax: 234 17677643 the proforma invoice must be sign and stam before our bank will honor it for payment. we are looking forward to hearing from you. 唯有按要求再一次 。隔了几天，到14号的时候，邮件又来了。 we thank you for mail and the attached proforma invoice. we he presented the proforma invoice to our financing bank for them to secure foreign exchange and process for the remittance in your for. we are expecting a confirmation from them within the day and will fax or scan to you a copy of the 50% deposit remittance slip immediately we receive further notice of the payment application in your for. we are looking forward for your kind cooperation. 请注意！他的付款方式好像还是按照他那样的：50% deposit remittance slip immediately we receive further notice of the payment application in your for。我就来疑问了，难道他没注意到pi上的付款方式吗？另外，之前的邮件也清楚地标明的。所以，我回复让他查看pi上的付款方式。现在等待他的回复。 今天15号。下午上班到差不多两点多的时候，邮件又来了。 we were notified us that the standard organization department of nigeria made necessary to present (1 pc) physical sample of each models as stated on the proforma invoice. this is one of the basic requirements by the micro finance firm for the sponsoring of imports involving related items. we would appreciate your immediate corporations to send the samples today by courier service to enable them proceed for the swift transfer of the payment to your account and we hope that you can continue to provide us with your products in the future. we are looking forward to hearing from you soon. 此邮件并没有对付款方式进行商讨，而是要求今天要样品。好。我就让他给到付账号看看。在等待回复中。。。。。。 备注：邮件来回从来没有商谈有关价格等的详情。过程也很顺利那样子。只是付款方面还待确认。另外pi得很急，也没有转换成pdf格式。那样会导致什么漏洞呢？如果他真的是骗子，他接下来可能要什么？ 小弟在此先感谢福友们的解答！ 谢谢！
