Benefits (or drawbacks) of ordering Euros from AAA (American Automobile Association) online [closed]

I am due to visit Europe on a Schengen visa for about a week in August. I was looking at various ways to get some petty cash (in Euros from USD) before flying.

Most of my expenditure will be paid for by an academic organization but I would still like some cash in my pocket. In addition, I have nice travel credit cards with no foreign transaction fees with me to use in an emergency.

Now, I have read a similar question on what some of the best practices are, in terms of exchanging USD to Euros. That question also touches on the fact that AAA type associations can also be used to exchange currency but does not explain the advantages or disadvantages of that approach vis-a-vis other approaches.

Since, I am an AAA member, I was wondering if any other AAA members or otherwise have any experience in ordering Euros from AAA online and if they could elaborate on the advantages and disadvantages of ordering from the AAA online versus other methods.

My ultimate objective is, as a student, to optimize my meagre finances when traveling in Europe.
