On the ingentis bom for the 20 x 20 aluminum profile it says to ask for 8pieces instead of six. Should I do this during checkout under the comments section or should I send the seller a message?

If you send the seller a message they are usually very helpful

That’s where I did it. The seller then emailed me to reconfirm and I gave them the exact dimensions, got exactly what I asked for.
