Gaming Club Nintendo coins and eShop purchases

[DiscostewSM]

I'd like to ask about this, but if I purchase an eShop game, do the coins from the purchase (if applicable) automatically get added to my account, or do I have to do a registration survey beforehand? If a survey is required, how long does that survey last before it expire? One other question. I recently got an XL (not registered yet), and I was planning on getting Luigi's Mansion. If I register both of these before 4/30, I'd be eligible for a free game of my choice from the selection. Does this free game also come with coins as if I had bought it separately?
The whole point of this topic is because right now, I have Platinum status with Club Nintendo for this time period (which ends June 30th, as the new cycle start July 1st), and I'm trying to save up as many coins as I can to be used for that next period. I'm thinking the XL registration adds the coins automatically while games have a time limit on registration via survey, but I also think those particular surveys don't last long. I have some Post-Play surveys that expire July 22nd, which is well within the limit for being used in the next cycle, but what about Registration surveys?

I usually don't check about things like this. I just do survey as they come and trust Nintendo is adding up points correctly. I believe you still have to do registration survey first before points are credited to your account. You have 30 days from the time you bought games from eShop to do registration survey.

Hmm, so I guess it's either 200 coins, or a free game. The choice is obvious in that regard.

For eshop games, you only get 10 coins for a post-play survey, which you can hold off for months on completing.
