Dutch to English Bus/Financial Finance (general)

This term appears in a Dutch source text, in the context of selecting various volumes of stocks to order:

e.g. Order à € 6.500, Order à € 10.000, Order à € 500.000

I have read that à in French can mean "to/up to", but this previous discussion of the term in a similar context suggests the opposite ("order from") to be the case here: https://www.proz.com/kudoz/french-to-english/internet-e-comm...

Any thoughts on what the best translation for this is? As a non-French speaker, I'm struggling a bit with the appearance of this in the Dutch text.

Thanks in advance for your help!
