(°) Payment should be performed after receipt of the invoice.
The invoice must be sent to:

以上内容什么意思？不大明白啊！！应该怎么回复比较合适？

2.PRICE LIST FOR REPRINTS
Reprints of articles which appear in ACTA CARDIOLOGICA are available at prices
determined by article lenght and quantity.
The minimum quantity is 50 reprints.
All prices are in euro, exclusive of VAT (if applicable) and shipping charges.
请问这是什么意思，这个用不用回复？
