Searching the USPTO Trademark ID Manual for promotional returns 302 accepted descriptions, and most of them sit in Class 35. The manual is the list of identifications the office has already approved, so wording taken from it is pre-approved and settles the class at the same time.

Promotional appears in 4 classes because what you make, what it is made of and the service of selling it are separate classes. Pick the descriptions above that match what you actually do.
Promotional is a service, so it sits in Classes 35 to 45. Software that delivers a service is often Class 9 or Class 42 as well.
Retail, advertising and business services: retail store services are here. The class covers the SERVICE of selling and never the goods sold, so a brand that makes what it sells needs the product class too.
The class decides what a registration covers; it does not decide whether the name is available. Relatedness is judged on the identifications, so a conflict can sit in a class you never looked at: the same name in a different industry.

You file in every class you actually use the mark in, and the USPTO charges its fee per class. Selling a product and also running an online store for it is two classes, not one. Filing in classes you do not use is worse than filing in too few: an application has to be supported by real use or a genuine intent to use.
No. The class decides what a registration covers. Availability turns on whether someone already holds a similar mark for related goods, and relatedness is judged on what the identifications say rather than on the class number, so marks in different classes can still conflict.
