I don't really have time to make a legit purchase first as I need the item for an upcoming trip.

The legit purchase Is not a necessity, so It's fine to go ahead with the SE as Is.

Do you think I should try the return method stated above or just do DNA?

You've stated that the DNA Is not an option for you.

It's not that it's not an option, it's just I like to minimise my use of the DNA method.

If I were to go DNA what is the order limit before an investigation is triggered?

There are no hard and fast rules.

Investigations can be triggered for Items as low as 40$.

Understood. The item I want to order is about $300.
