Selling and Sales

[Blackbarry]

Double doubt this Sunday...

What's the different meaning of the two sentences below, and why is the second wrong provided that both sale and selling mean a transaction?

the print shop hasn't finished printing our sales materials yet!

Thanks in advance for your helping hand!

Sales materials are materials used to help sell things like pamphlets, advertisements, informational packets etc.

Selling materials isn't a collocation I've ever heard.

 

[Barque]

"Sale" and "Selling" may both refer to a sale transaction but they are different forms of the word "sell".

"Sales materials" is a fairly common term meaning materials used in sales like brochures and pamphlets.
"Selling materials" isn't used that way. If I heard this term used I would think the speaker was referring to the things that he sold.

Cross-posted.

Burning materials = materials that are burning.
selling materials = materials that are selling.

Sales materials = materials that are associated with the activity of sales.
