由于之前的试订货效果不错，买方这次决定正式订货。这就是一封确认信（Letter of confirmation），确认自己订购的货物数量及价格。
We confirm our formal order for 500 pairs of fashionable shoes at HK$ 55.00 a pair.
We regret that our lack of any inquiries has brought you some concern and inconvenience, due to an accumulation of stock and not due to any question of your goods or your service.
Your new catalogue and your brochure will, of course, continue to have our best attention.
Yours faithfully,
